  text: Many adult tissues contain postmitotic cells as old as the host organism.
    The only organelle that does not turn over in these cells is the nucleus, and
    its maintenance represents a formidable challenge, as it harbors regulatory proteins
    that persist throughout adulthood. Here we developed strategies to visualize two
    classes of such long-lived proteins, histones and nucleoporins, to understand
    the function of protein longevity in nuclear maintenance. Genome-wide mapping
    of histones revealed specific enrichment of long-lived variants at silent gene
    loci. Interestingly, nuclear pores are maintained by piecemeal replacement of
    subunits, resulting in mosaic complexes composed of polypeptides with vastly different
    ages. In contrast, nondividing quiescent cells remove old nuclear pores in an
    ESCRT-dependent manner. Our findings reveal distinct molecular strategies of nuclear
    maintenance, linking lifelong protein persistence to gene regulation and nuclear
    integrity.

  text: Most neurons are not replaced during an animal’s lifetime. This nondividing
    state is characterized by extreme longevity and age-dependent decline of key regulatory
    proteins. To study the lifespans of cells and proteins in adult tissues, we combined
    isotope labeling of mice with a hybrid imaging method (MIMS-EM). Using 15N mapping,
    we show that liver and pancreas are composed of cells with vastly different ages,
    many as old as the animal. Strikingly, we also found that a subset of fibroblasts
    and endothelial cells, both known for their replicative potential, are characterized
    by the absence of cell division during adulthood. In addition, we show that the
    primary cilia of beta cells and neurons contains different structural regions
    with vastly different lifespans. Based on these results, we propose that age mosaicism
    across multiple scales is a fundamental principle of adult tissue, cell, and protein
    complex organization.

  text: Deep optical spectroscopic surveys of galaxies provide a unique opportunity
    to investigate rest-frame ultra-violet (UV) emission line properties of galaxies
    at z ∼ 2 − 4.5. Here we combine VLT/MUSE Guaranteed Time Observations of the Hubble
    Deep Field South, Ultra Deep Field, COSMOS, and several quasar fields with other
    publicly available data from VLT/VIMOS and VLT/FORS2 to construct a catalogue
    of He II λ1640 emitters at z ≳ 2. The deepest areas of our MUSE pointings reach
    a 3σ line flux limit of 3.1 × 10−19 erg s−1 cm−2. After discarding broad-line
    active galactic nuclei, we find 13 He II λ1640 detections from MUSE with a median
    MUV = −20.1 and 21 tentative He II λ1640 detections from other public surveys.
    Excluding Lyα, all except two galaxies in our sample show at least one other rest-UV
    emission line, with C III] λ1907, λ1909 being the most prominent. We use multi-wavelength
    data available in the Hubble legacy fields to derive basic galaxy properties of
    our sample through spectral energy distribution fitting techniques. Taking advantage
    of the high-quality spectra obtained by MUSE (∼10 − 30 h of exposure time per
    pointing), we use photo-ionisation models to study the rest-UV emission line diagnostics
    of the He II λ1640 emitters. Line ratios of our sample can be reproduced by moderately
    sub-solar photo-ionisation models, however, we find that including effects of
    binary stars lead to degeneracies in most free parameters. Even after considering
    extra ionising photons produced by extreme sub-solar metallicity binary stellar
    models, photo-ionisation models are unable to reproduce rest-frame He II λ1640
    equivalent widths (∼0.2 − 10 Å), thus additional mechanisms are necessary in models
    to match the observed He II λ1640 properties.

  text: "Contact. This paper presents the results obtained with the Multi-Unit Spectroscopic
    Explorer (MUSE) at the ESO Very Large Telescope on the faint end of the Lyman-alpha
    luminosity function (LF) based on deep observations of four lensing clusters.
    The goal of our project is to set strong constraints on the relative contribution
    of the Lyman-alpha emitter (LAE) population to cosmic reionization.\r\n\r\nAims.
    The precise aim of the present study is to further constrain the abundance of
    LAEs by taking advantage of the magnification provided by lensing clusters to
    build a blindly selected sample of galaxies which is less biased than current
    blank field samples in redshift and luminosity. By construction, this sample of
    LAEs is complementary to those built from deep blank fields, whether observed
    by MUSE or by other facilities, and makes it possible to determine the shape of
    the LF at fainter levels, as well as its evolution with redshift.\r\n\r\nMethods.
    We selected a sample of 156 LAEs with redshifts between 2.9 ≤ z ≤ 6.7 and magnification-corrected
    luminosities in the range 39 ≲ log LLyα [erg s−1] ≲43. To properly take into account
    the individual differences in detection conditions between the LAEs when computing
    the LF, including lensing configurations, and spatial and spectral morphologies,
    the non-parametric 1/Vmax method was adopted. The price to pay to benefit from
    magnification is a reduction of the effective volume of the survey, together with
    a more complex analysis procedure to properly determine the effective volume Vmax
    for each galaxy. In this paper we present a complete procedure for the determination
    of the LF based on IFU detections in lensing clusters. This procedure, including
    some new methods for masking, effective volume integration and (individual) completeness
    determinations, has been fully automated when possible, and it can be easily generalized
    to the analysis of IFU observations in blank fields.\r\n\r\nResults. As a result
    of this analysis, the Lyman-alpha LF has been obtained in four different redshift
    bins: 2.9 <  z <  6, 7, 2.9 <  z <  4.0, 4.0 <  z <  5.0, and 5.0 <  z <  6.7
    with constraints down to log LLyα = 40.5. From our data only, no significant evolution
    of LF mean slope can be found. When performing a Schechter analysis also including
    data from the literature to complete the present sample towards the brightest
    luminosities, a steep faint end slope was measured varying from α = −1.69−0.08+0.08
    to α = −1.87−0.12+0.12 between the lowest and the highest redshift bins.\r\n\r\nConclusions.
    The contribution of the LAE population to the star formation rate density at z ∼ 6
    is ≲50% depending on the luminosity limit considered, which is of the same order
    as the Lyman-break galaxy (LBG) contribution. The evolution of the LAE contribution
    with redshift depends on the assumed escape fraction of Lyman-alpha photons, and
    appears to slightly increase with increasing redshift when this fraction is conservatively
    set to one. Depending on the intersection between the LAE/LBG populations, the
    contribution of the observed galaxies to the ionizing flux may suffice to keep
    the universe ionized at z ∼ 6."

  text: 'Lyman-α (Lyα) is intrinsically the brightest line emitted from active galaxies.
    While it originates from many physical processes, for star-forming galaxies the
    intrinsic Lyα luminosity is a direct tracer of the Lyman-continuum (LyC) radiation
    produced by the most massive O- and early-type B-stars (M⋆ ≳ 10 M⊙) with lifetimes
    of a few Myrs. As such, Lyα luminosity should be an excellent instantaneous star
    formation rate (SFR) indicator. However, its resonant nature and susceptibility
    to dust as a rest-frame UV photon makes Lyα very hard to interpret due to the
    uncertain Lyα escape fraction, fesc, Lyα. Here we explore results from the CAlibrating
    LYMan-α with Hα (CALYMHA) survey at z = 2.2, follow-up of Lyα emitters (LAEs)
    at z = 2.2 − 2.6 and a z ∼ 0−0.3 compilation of LAEs to directly measure fesc, Lyα
    with Hα. We derive a simple empirical relation that robustly retrieves fesc, Lyα
    as a function of Lyα rest-frame EW (EW0): fesc,Lyα = 0.0048 EW0[Å] ± 0.05 and
    we show that it constrains a well-defined anti-correlation between ionisation
    efficiency (ξion) and dust extinction in LAEs. Observed Lyα luminosities and EW0
    are easy measurable quantities at high redshift, thus making our relation a practical
    tool to estimate intrinsic Lyα and LyC luminosities under well controlled and
    simple assumptions. Our results allow observed Lyα luminosities to be used to
    compute SFRs for LAEs at z ∼ 0−2.6 within ±0.2 dex of the Hα dust corrected SFRs.
    We apply our empirical SFR(Lyα,EW0) calibration to several sources at z ≥ 2.6
    to find that star-forming LAEs have SFRs typically ranging from 0.1 to 20 M⊙ yr−1
    and that our calibration might be even applicable for the most luminous LAEs within
    the epoch of re-ionisation. Our results imply high ionisation efficiencies (log10[ξion/Hz erg−1]
    = 25.4−25.6) and low dust content in LAEs across cosmic time, and will be easily
    tested with future observations with JWST which can obtain Hα and Hβ measurements
    for high-redshift LAEs.'

  text: We discuss the nature and physical properties of gas-mass selected galaxies
    in the ALMA spectroscopic survey (ASPECS) of the Hubble Ultra Deep Field (HUDF).
    We capitalize on the deep optical integral-field spectroscopy from the Multi Unit
    Spectroscopic Explorer (MUSE) HUDF Survey and multiwavelength data to uniquely
    associate all 16 line emitters, detected in the ALMA data without preselection,
    with rotational transitions of carbon monoxide (CO). We identify 10 as CO(2–1)
    at 1 < z < 2, 5 as CO(3–2) at 2 < z < 3, and 1 as CO(4–3) at z = 3.6. Using the
    MUSE data as a prior, we identify two additional CO(2–1) emitters, increasing
    the total sample size to 18. We infer metallicities consistent with (super-)solar
    for the CO-detected galaxies at z ≤ 1.5, motivating our choice of a Galactic conversion
    factor between CO luminosity and molecular gas mass for these galaxies. Using
    deep Chandra imaging of the HUDF, we determine an X-ray AGN fraction of 20% and
    60% among the CO emitters at z ∼ 1.4 and z ∼ 2.6, respectively. Being a CO-flux-limited
    survey, ASPECS-LP detects molecular gas in galaxies on, above, and below the main
    sequence (MS) at z ∼ 1.4. For stellar masses ≥1010 (1010.5) ${M}_{\odot }$, we
    detect about 40% (50%) of all galaxies in the HUDF at 1 < z < 2 (2 < z < 3). The
    combination of ALMA and MUSE integral-field spectroscopy thus enables an unprecedented
    view of MS galaxies during the peak of galaxy formation.

  text: We present new deep ALMA and Hubble Space Telescope (HST)/WFC3 observations
    of MASOSA and VR7, two luminous Lyα emitters (LAEs) at z = 6.5, for which the
    UV continuum levels differ by a factor of four. No IR dust continuum emission
    is detected in either, indicating little amounts of obscured star formation and/or
    high dust temperatures. MASOSA, with a UV luminosity M1500 = −20.9, compact size,
    and very high Lyα ${\mathrm{EW}}_{0}\approx 145\,\mathring{\rm A} $, is undetected
    in [C ii] to a limit of L[C ii] < 2.2 × 107 L⊙, implying a metallicity Z ≲ 0.07
    Z⊙. Intriguingly, our HST data indicate a red UV slope β = −1.1 ± 0.7, at odds
    with the low dust content. VR7, which is a bright (M1500 = −22.4) galaxy with
    moderate color (β = −1.4 ± 0.3) and Lyα EW0 = 34 Å, is clearly detected in [C
    ii] emission (S/N = 15). VR7's rest-frame UV morphology can be described by two
    components separated by ≈1.5 kpc and is globally more compact than the [C ii]
    emission. The global [C ii]/UV ratio indicates Z ≈ 0.2 Z⊙, but there are large
    variations in the UV/[C ii] ratio on kiloparsec scales. We also identify diffuse,
    possibly outflowing, [C ii]-emitting gas at ≈100 km s−1 with respect to the peak.
    VR7 appears to be assembling its components at a slightly more evolved stage than
    other luminous LAEs, with outflows already shaping its direct environment at z
    ∼ 7. Our results further indicate that the global [C ii]−UV relation steepens
    at SFR < 30 M⊙ yr−1, naturally explaining why the [C ii]/UV ratio is anticorrelated
    with Lyα EW in many, but not all, observed LAEs.

  text: The well-known quasar SDSS J095253.83+011421.9 (J0952+0114) at z = 3.02 has
    one of the most peculiar spectra discovered so far, showing the presence of narrow
    Lyα and broad metal emission lines. Although recent studies have suggested that
    a proximate damped Lyα absorption (PDLA) system causes this peculiar spectrum,
    the origin of the gas associated with the PDLA is unknown. Here we report the
    results of observations with the Multi Unit Spectroscopic Explorer (MUSE) that
    reveal a new giant (≈100 physical kpc) Lyα nebula. The detailed analysis of the
    Lyα velocity, velocity dispersion, and surface brightness profiles suggests that
    the J0952+0114 Lyα nebula shares similar properties with other QSO nebulae previously
    detected with MUSE, implying that the PDLA in J0952+0144 is covering only a small
    fraction of the solid angle of the QSO emission. We also detected bright and spectrally
    narrow C iv λ1550 and He ii λ1640 extended emission around J0952+0114 with velocity
    centroids similar to the peak of the extended and central narrow Lyα emission.
    The presence of a peculiarly bright, unresolved, and relatively broad He ii λ1640
    emission in the central region at exactly the same PDLA redshift hints at the
    possibility that the PDLA originates in a clumpy outflow with a bulk velocity
    of about 500 km s−1. The smaller velocity dispersion of the large-scale Lyα emission
    suggests that the high-speed outflow is confined to the central region. Lastly,
    the derived spatially resolved He ii/Lyα and C iv/Lyα maps show a positive gradient
    with the distance to the QSO, hinting at a non-homogeneous distribution of the
    ionization parameter.

  text: To understand star formation in galaxies, we investigate the star formation
    rate (SFR) surface density (ΣSFR) profiles for galaxies, based on a well-defined
    sample of 976 star-forming MaNGA galaxies. We find that the typical ΣSFR profiles
    within 1.5Re of normal SF galaxies can be well described by an exponential function
    for different stellar mass intervals, while the sSFR profile shows positive gradients,
    especially for more massive SF galaxies. This is due to the more pronounced central
    cores or bulges rather than the onset of a `quenching' process. While galaxies
    that lie significantly above (or below) the star formation main sequence (SFMS)
    show overall an elevation (or suppression) of ΣSFR at all radii, this central
    elevation (or suppression) is more pronounced in more massive galaxies. The degree
    of central enhancement and suppression is quite symmetric, suggesting that both
    the elevation and suppression of star formation are following the same physical
    processes. Furthermore, we find that the dispersion in ΣSFR within and across
    the population is found to be tightly correlated with the inferred gas depletion
    time, whether based on the stellar surface mass density or the orbital dynamical
    time. This suggests that we are seeing the response of a simple gas-regulator
    system to variations in the accretion rate. This is explored using a heuristic
    model that can quantitatively explain the dependence of σ(ΣSFR) on gas depletion
    timescale. Variations in accretion rate are progressively more damped out in regions
    of low star-formation efficiency leading to a reduced amplitude of variations
    in star-formation.

  text: We investigate the clustering and halo properties of ∼5000 Ly α-selected emission-line
    galaxies (LAEs) from the Slicing COSMOS 4K (SC4K) and from archival NB497 imaging
    of SA22 split in 15 discrete redshift slices between z ∼ 2.5 and 6. We measure
    clustering lengths of r0 ∼ 3–6 h−1 Mpc and typical halo masses of ∼1011 M⊙ for
    our narrowband-selected LAEs with typical LLy α ∼ 1042–43 erg s−1. The intermediate-band-selected
    LAEs are observed to have r0 ∼ 3.5–15 h−1 Mpc with typical halo masses of ∼1011–12
    M⊙ and typical LLy α ∼ 1043–43.6 erg s−1. We find a strong, redshift-independent
    correlation between halo mass and Ly α luminosity normalized by the characteristic
    Ly α luminosity, L⋆(z). The faintest LAEs (L ∼ 0.1 L⋆(z)) typically identified
    by deep narrowband surveys are found in 1010 M⊙ haloes and the brightest LAEs
    (L ∼ 7 L⋆(z)) are found in ∼5 × 1012 M⊙ haloes. A dependency on the rest-frame
    1500 Å UV luminosity, MUV, is also observed where the halo masses increase from
    1011 to 1013 M⊙ for MUV ∼ −19 to −23.5 mag. Halo mass is also observed to increase
    from 109.8 to 1012 M⊙ for dust-corrected UV star formation rates from ∼0.6 to
    10 M⊙ yr−1 and continues to increase up to 1013 M⊙ in halo mass, where the majority
    of those sources are active galactic nuclei. All the trends we observe are found
    to be redshift independent. Our results reveal that LAEs are the likely progenitors
    of a wide range of galaxies depending on their luminosity, from dwarf-like, to
    Milky Way-type, to bright cluster galaxies. LAEs therefore provide unique insight
    into the early formation and evolution of the galaxies we observe in the local
    Universe.

  text: Observations have revealed that the star formation rate (SFR) and stellar
    mass (Mstar) of star-forming galaxies follow a tight relation known as the galaxy
    main sequence. However, what physical information is encoded in this relation
    is under debate. Here, we use the EAGLE cosmological hydrodynamical simulation
    to study the mass dependence, evolution, and origin of scatter in the SFR–Mstar
    relation. At z = 0, we find that the scatter decreases slightly with stellar mass
    from 0.35 dex at Mstar ≈ 109 M⊙ to 0.30 dex at Mstar ≳ 1010.5 M⊙. The scatter
    decreases from z = 0 to z = 5 by 0.05 dex at Mstar ≳ 1010 M⊙ and by 0.15 dex for
    lower masses. We show that the scatter at z = 0.1 originates from a combination
    of fluctuations on short time-scales (ranging from 0.2–2 Gyr) that are presumably
    associated with self-regulation from cooling, star formation, and outflows, but
    is dominated by long time-scale (∼10 Gyr) variations related to differences in
    halo formation times. Shorter time-scale fluctuations are relatively more important
    for lower mass galaxies. At high masses, differences in black hole formation efficiency
    cause additional scatter, but also diminish the scatter caused by different halo
    formation times. While individual galaxies cross the main sequence multiple times
    during their evolution, they fluctuate around tracks associated with their halo
    properties, i.e. galaxies above/below the main sequence at z = 0.1 tend to have
    been above/below the main sequence for ≫1 Gyr.

  text: We present new Hubble Space Telescope (HST)/WFC3 observations and re-analyse
    VLT data to unveil the continuum, variability, and rest-frame ultraviolet (UV)
    lines of the multiple UV clumps of the most luminous Lyα emitter at z = 6.6, CR7
    (COSMOS Redshift 7). Our re-reduced, flux-calibrated X-SHOOTER spectra of CR7
    reveal an He II emission line in observations obtained along the major axis of
    Lyα emission with the best seeing conditions. He II is spatially offset by ≈+0.8
    arcsec from the peak of Lyα emission, and it is found towards clump B. Our WFC3
    grism spectra detects the UV continuum of CR7’s clump A, yielding a power law
    with β=−2.5+0.6−0.7 and MUV=−21.87+0.25−0.20⁠. No significant variability is found
    for any of the UV clumps on their own, but there is tentative (≈2.2 σ) brightening
    of CR7 in F110W as a whole from 2012 to 2017. HST grism data fail to robustly
    detect rest-frame UV lines in any of the clumps, implying fluxes ≲2×10−17 erg s−1 cm−2
    (3σ). We perform CLOUDY modelling to constrain the metallicity and the ionizing
    nature of CR7. CR7 seems to be actively forming stars without any clear active
    galactic nucleus activity in clump A, consistent with a metallicity of ∼0.05–0.2 Z⊙.
    Component C or an interclump component between B and C may host a high ionization
    source. Our results highlight the need for spatially resolved information to study
    the formation and assembly of early galaxies.

  text: Over 2,000 stars were observed for 1 month with a high enough cadence in order
    to look for acoustic modes during the survey phase of the Kepler mission. Solar-like
    oscillations have been detected in about 540 stars. The question of why no oscillations
    were detected in the remaining stars is still open. Previous works explained the
    non-detection of modes with the high level of magnetic activity of the stars.
    However, the sample of stars studied contained some classical pulsators and red
    giants that could have biased the results. In this work, we revisit this analysis
    on a cleaner sample of main-sequence solar-like stars that consists of 1,014 stars.
    First we compute the predicted amplitude of the modes of that sample and for the
    stars with detected oscillation and compare it to the noise at high frequency
    in the power spectrum. We find that the stars with detected modes have an amplitude
    to noise ratio larger than 0.94. We measure reliable rotation periods and the
    associated photometric magnetic index for 684 stars out of the full sample and
    in particular for 323 stars where the amplitude of the modes is predicted to be
    high enough to be detected. We find that among these 323 stars 32% of them have
    a level of magnetic activity larger than the Sun during its maximum activity,
    explaining the non-detection of acoustic modes. Interestingly, magnetic activity
    cannot be the primary reason responsible for the absence of detectable modes in
    the remaining 68% of the stars without acoustic modes detected and with reliable
    rotation periods. Thus, we investigate metallicity, inclination angle of the rotation
    axis, and binarity as possible causes of low mode amplitudes. Using spectroscopic
    observations for a subsample, we find that a low metallicity could be the reason
    for suppressed modes. No clear correlation with binarity nor inclination is found.
    We also derive the lower limit for our photometric activity index (of 20–30 ppm)
    below which rotation and magnetic activity are not detected. Finally, with our
    analysis we conclude that stars with a photometric activity index larger than
    2,000 ppm have 98.3% probability of not having oscillations detected.

  text: The NASA Transiting Exoplanet Survey Satellite (TESS) is about to provide
    full-frame images of almost the entire sky. The amount of stellar data to be analysed
    represents hundreds of millions stars, which is several orders of magnitude more
    than the number of stars observed by the Convection, Rotation and planetary Transits
    satellite (CoRoT), and NASA Kepler and K2 missions. We aim at automatically classifying
    the newly observed stars with near real-time algorithms to better guide the subsequent
    detailed studies. In this paper, we present a classification algorithm built to
    recognise solar-like pulsators among classical pulsators. This algorithm relies
    on the global amount of power contained in the power spectral density (PSD), also
    known as the flicker in spectral power density (FliPer). Because each type of
    pulsating star has a characteristic background or pulsation pattern, the shape
    of the PSD at different frequencies can be used to characterise the type of pulsating
    star. The FliPer classifier (FliPerClass) uses different FliPer parameters along
    with the effective temperature as input parameters to feed a ML algorithm in order
    to automatically classify the pulsating stars observed by TESS. Using noisy TESS-simulated
    data from the TESS Asteroseismic Science Consortium (TASC), we classify pulsators
    with a 98% accuracy. Among them, solar-like pulsating stars are recognised with
    a 99% accuracy, which is of great interest for a further seismic analysis of these
    stars, which are like our Sun. Similar results are obtained when we trained our
    classifier and applied it to 27-day subsets of real Kepler data. FliPerClass is
    part of the large TASC classification pipeline developed by the TESS Data for
    Asteroseismology (T’DA) classification working group.

  text: The recently published Kepler mission Data Release 25 (DR25) reported on ∼197 000
    targets observed during the mission. Despite this, no wide search for red giants
    showing solar-like oscillations have been made across all stars observed in Kepler’s
    long-cadence mode. In this work, we perform this task using custom apertures on
    the Kepler pixel files and detect oscillations in 21 914 stars, representing the
    largest sample of solar-like oscillating stars to date. We measure their frequency
    at maximum power, νmax, down to νmax≃4μHz and obtain log (g) estimates with a
    typical uncertainty below 0.05 dex, which is superior to typical measurements
    from spectroscopy. Additionally, the νmax distribution of our detections show
    good agreement with results from a simulated model of the Milky Way, with a ratio
    of observed to predicted stars of 0.992 for stars with 10<νmax<270μHz. Among our
    red giant detections, we find 909 to be dwarf/subgiant stars whose flux signal
    is polluted by a neighbouring giant as a result of using larger photometric apertures
    than those used by the NASA Kepler science processing pipeline. We further find
    that only 293 of the polluting giants are known Kepler targets. The remainder
    comprises over 600 newly identified oscillating red giants, with many expected
    to belong to the Galactic halo, serendipitously falling within the Kepler pixel
    files of targeted stars.

  text: We present the discovery of HD 221416 b, the first transiting planet identified
    by the Transiting Exoplanet Survey Satellite (TESS) for which asteroseismology
    of the host star is possible. HD 221416 b (HIP 116158, TOI-197) is a bright (V
    = 8.2 mag), spectroscopically classified subgiant that oscillates with an average
    frequency of about 430 μHz and displays a clear signature of mixed modes. The
    oscillation amplitude confirms that the redder TESS bandpass compared to Kepler
    has a small effect on the oscillations, supporting the expected yield of thousands
    of solar-like oscillators with TESS 2 minute cadence observations. Asteroseismic
    modeling yields a robust determination of the host star radius (R⋆ = 2.943 ± 0.064
    R⊙), mass (M⋆ = 1.212 ± 0.074 M⊙), and age (4.9 ± 1.1 Gyr), and demonstrates that
    it has just started ascending the red-giant branch. Combining asteroseismology
    with transit modeling and radial-velocity observations, we show that the planet
    is a "hot Saturn" (Rp = 9.17 ± 0.33 R⊕) with an orbital period of ∼14.3 days,
    irradiance of F = 343 ± 24 F⊕, and moderate mass (Mp = 60.5 ± 5.7 M⊕) and density
    (ρp = 0.431 ± 0.062 g cm−3). The properties of HD 221416 b show that the host-star
    metallicity–planet mass correlation found in sub-Saturns (4–8 R⊕) does not extend
    to larger radii, indicating that planets in the transition between sub-Saturns
    and Jupiters follow a relatively narrow range of densities. With a density measured
    to ∼15%, HD 221416 b is one of the best characterized Saturn-size planets to date,
    augmenting the small number of known transiting planets around evolved stars and
    demonstrating the power of TESS to characterize exoplanets and their host stars
    using asteroseismology.

  text: Brightness variations due to dark spots on the stellar surface encode information
    about stellar surface rotation and magnetic activity. In this work, we analyze
    the Kepler long-cadence data of 26,521 main-sequence stars of spectral types M
    and K in order to measure their surface rotation and photometric activity level.
    Rotation-period estimates are obtained by the combination of a wavelet analysis
    and autocorrelation function of the light curves. Reliable rotation estimates
    are determined by comparing the results from the different rotation diagnostics
    and four data sets. We also measure the photometric activity proxy Sph using the
    amplitude of the flux variations on an appropriate timescale. We report rotation
    periods and photometric activity proxies for about 60% of the sample, including
    4431 targets for which McQuillan et al. did not report a rotation period. For
    the common targets with rotation estimates in this study and in McQuillan et al.,
    our rotation periods agree within 99%. In this work, we also identify potential
    polluters, such as misclassified red giants and classical pulsator candidates.
    Within the parameter range we study, there is a mild tendency for hotter stars
    to have shorter rotation periods. The photometric activity proxy spans a wider
    range of values with increasing effective temperature. The rotation period and
    photometric activity proxy are also related, with Sph being larger for fast rotators.
    Similar to McQuillan et al., we find a bimodal distribution of rotation periods.

  text: 'For a solar-like star, the surface rotation evolves with time, allowing in
    principle to estimate the age of a star from its surface rotation period. Here
    we are interested in measuring surface rotation periods of solar-like stars observed
    by the NASA mission Kepler. Different methods have been developed to track rotation
    signals in Kepler photometric light curves: time-frequency analysis based on wavelet
    techniques, autocorrelation and composite spectrum. We use the learning abilities
    of random forest classifiers to take decisions during two crucial steps of the
    analysis. First, given some input parameters, we discriminate the considered Kepler
    targets between rotating MS stars, non-rotating MS stars, red giants, binaries
    and pulsators. We then use a second classifier only on the MS rotating targets
    to decide the best data analysis treatment.'

  text: 'The second mission of NASA’s Kepler satellite, K2, has collected hundreds
    of thousands of lightcurves for stars close to the ecliptic plane. This new sample
    could increase the number of known pulsating stars and then improve our understanding
    of those stars. For the moment only a few stars have been properly classified
    and published. In this work, we present a method to automaticly classify K2 pulsating
    stars using a Machine Learning technique called Random Forest. The objective is
    to sort out the stars in four classes: red giant (RG), main-sequence Solar-like
    stars (SL), classical pulsators (PULS) and Other. To do this we use the effective
    temperatures and the luminosities of the stars as well as the FliPer features,
    that measures the amount of power contained in the power spectral density. The
    classifier now retrieves the right classification for more than 80% of the stars.'
