    Weak Galactic halo-Fornax dSph connection from RR Lyrae stars
    Aims: For the first time accurate pulsation properties of the ancient variable stars of the Fornax dwarf spheroidal galaxy (dSph) are discussed in the broad...
  • Publication
    Westerlund 1 under the light of Gaia EDR3: Distance, isolation, extent, and a hidden population
    Context. The young massive cluster Westerlund 1 offers the promise of a grand laboratory for the study of high-mass star evolution, but its basic parameters are...
  • Publication
    What is the Milky Way outer halo made of?. High resolution spectroscopy of distant red giants
    In a framework where galaxies form hierarchically, extended stellar haloes are predicted to be an ubiquitous feature around Milky Way-like galaxies and to...
  • Publication
    When binaries keep track of recent nucleosynthesis. The Zr-Nb pair in extrinsic stars as an s-process diagnostic
    Context. Barium stars are s-process enriched giants. They owe their chemical peculiarities to a past mass transfer phase. During this phase they were polluted...

    Where does galactic dust come from?
    Here we investigate the origin of the dust mass (Mdust) observed in the Milky Way (MW) and of dust scaling relations found in a sample of local galaxies from...
  • Publication
    Wide binaries in planetary nebulae with Gaia DR2
    Context. The Gaia Data Release 2 (DR2) was used to select a sample of 211 central stars of planetary nebulae (CSPNe) with good-quality astrometric measurements...
  • Publication
    Wind Diagnostic from Infrared Lines
    For the large population of massive stars lying behind dust, among which are the youngests and potentially the most massive of our Galaxy, none of the commonly...

    Winds of Low-metallicity OB-type Stars: HST-COS Spectroscopy in IC 1613
    We present the first quantitative ultraviolet spectroscopic analysis of resolved OB stars in IC 1613. Because of its alleged very low metallicity (lsim1/10 Z ☉...

    WSO and the winds of massive stars: the gate to the metal-poor Local Universe
    The spectrographs on-board the World Space Observatory (WSO) will provide access to the 1020-1800 Å wavelength range with unprecedented sensitivity. Previous...
