    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...

    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-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...

    The Mice at play in the CALIFA survey. A case study of a gas-rich major merger between first passage and coalescence
    We present optical integral field spectroscopy (IFS) observations of the Mice, a major merger between two massive (≳1011 M⊙) gas-rich spirals NGC 4676A and B...
