    The R136 star cluster dissected with Hubble Space Telescope/STIS - II. Physical properties of the most massive stars in R136
    We present an optical analysis of 55 members of R136, the central cluster in the Tarantula Nebula of the Large Magellanic Cloud. Our sample was observed with...

    The radial abundance gradient of chlorine in the Milky Way
    We determine the radial abundance gradient of Cl in the Milky Way from H II regions spectra. For the first time, the Cl/H ratios are computed by simply adding...

    The radial abundance gradient of oxygen towards the Galactic anti-centre
    We present deep optical spectroscopy of eight H II regions located in the anti-centre of the Milky Way. The spectra were obtained at the 10.4 m GTC and 8.2 m...

    The Recent Star Formation History of NGC 5102
    We present Hubble Space Telescope photometry of young stars in NGC 5102, a nearby gas-rich post-starburst S0 galaxy with a bright young stellar nucleus. We use...

    The recurrent impact of the Sagittarius dwarf on the star formation history of the Milky Way
    Satellites orbiting disk galaxies can induce phase space features such as spirality, vertical heating and phase-mixing in their disks. Such features have also...

    The Resolved Stellar Populations in the LEGUS Galaxies1
    The Legacy ExtraGalactic UV Survey (LEGUS) is a multiwavelength Cycle 21 Treasury program on the Hubble Space Telescope. It studied 50 nearby star-forming...

    The role of massive AGB stars in the early solar system composition
    We demonstrate that a massive asymptotic giant branch (AGB) star is a good candidate as the main source of short-lived radionuclides in the early solar system...

    The rotation rates of massive stars. How slow are the slow ones?
    Context. Rotation plays a key role in the life cycles of stars with masses above ~8 M⊙. Hence, accurate knowledge of the rotation rates of such massive stars is...

    The SDSS-III APOGEE Spectral Line List for H-band Spectroscopy
    We present the H-band spectral line lists adopted by the Apache Point Observatory Galactic Evolution Experiment (APOGEE). The APOGEE line lists comprise...
