    The merger rate of extremely low mass white dwarf binaries: links to the formation of AM CVn stars and underluminous supernovae
    We study a complete, colour-selected sample of double-degenerate binary systems containing extremely low mass (ELM) ≤0.25 M&sun; white dwarfs (WDs). We show...
  • Publication
    The merging/AGN connection. II. Ionization of the circumnuclear regions
    We report the first results of a study of a sample of 20 galaxy mergers/interacting systems, using the VIMOS and PMAS integral field spectrographs. For each...

    The messy death of a multiple star system and the resulting planetary nebula as observed by JWST
    Planetary nebulae—the ejected envelopes of red giant stars—provide us with a history of the last, mass-losing phases of 90% of stars initially more massive than...

    The metal content of GR 8 and Sextans B
    Ionic abundances for two irregular dwarf galaxies belonging to the Local Group, GR 8 and Sextans B, are presented. The oxygen abundances have been found to be 0...

    The metal-poor edge of the Milky Way's "thin disc"
    Context. The emergence of the disc in our Galaxy and the relation between thick and thin disc formation and evolution is still a matter of debate. The chemo...
  • Publication
    The metal-poor end of the Spite plateau. I. Stellar parameters, metallicities, and lithium abundances
    Context. The primordial nature of the Spite plateau is at odds with the WMAP satellite measurements, implying a primordial Li production at least three times...

    The Metal-poor non-Sagittarius (?) Globular Cluster NGC 5053: Orbit and Mg, Al, and Si Abundances
    Metal-poor globular clusters (GCs) exhibit intriguing Al–Mg anti-correlations and possible Si–Al correlations, which are important clues to decipher the...

    The metal-rich halo tail extended in |z|: a characterization with Gaia DR2 and APOGEE
    We report an analysis of the metal-rich tail ([Fe/H] > -0.75) of stars located at distances from the Galactic plane up to |z| ˜ 10 kpc, observed by the Apache...

    The metal-rich nature of stars with planets
    With the goal of confirming the metallicity ``excess'' present in stars with planetary-mass companions, we present in this paper a high-precision spectroscopic...
