    Water-ice-driven Activity on Main-Belt Comet P/2010 A2 (LINEAR)?
    The dust ejecta of Main-Belt Comet P/2010 A2 (LINEAR) have been observed with several telescopes at the Observatorio del Roque de los Muchachos on La Palma...

    Weak Galactic Halo-Dwarf Spheroidal Connection from RR Lyrae Stars
    We discuss the role that dwarf galaxies may have played in the formation of the Galactic halo (Halo) using RR Lyrae stars (RRL) as tracers of their ancient...

    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...

    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...

    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...

    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...

    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...
