    Chemical analysis of very metal-poor turn-off stars from SDSS-DR12
    Context. The most metal-poor stars are the relics of the early chemical evolution of the Galaxy. Their chemical composition is an important tool to constrain...
  • Publication
    Chemical and Kinematic Analysis of CN-strong Metal-poor Field Stars in LAMOST DR3
    The large amount of chemical and kinematic information available in large spectroscopic surveys has inspired the search for chemically peculiar stars in the...

    Chemical behavior of the dwarf irregular galaxy NGC6822. Its PN and HII region abundances
    Aims: We aim to derive the chemical behavior of a significant sample of PNe and HII regions in the irregular galaxy NGC 6822. The selected objects are...

    Chemical Cartography with APOGEE: Large-scale Mean Metallicity Maps of the Milky Way Disk
    We present Galactic mean metallicity maps derived from the first year of the SDSS-III APOGEE experiment. Mean abundances in different zones of projected...
  • Publication
    Chemical Cartography with APOGEE: Mapping Disk Populations with a 2-process Model and Residual Abundances
    We apply a novel statistical analysis to measurements of 16 elemental abundances in 34,410 Milky Way disk stars from the final data release (DR17) of APOGEE-2...
  • Publication
    Chemical Cartography with APOGEE: Metallicity Distribution Functions and the Chemical Structure of the Milky Way Disk
    Using a sample of 69,919 red giants from the SDSS-III/APOGEE Data Release 12, we measure the distribution of stars in the [α/Fe] versus [Fe/H] plane and the...
  • Publication
    Chemical Cartography with APOGEE: Multi-element Abundance Ratios
    We map the trends of elemental abundance ratios across the Galactic disk, spanning R=3{--}15 {kpc} and midplane distance | Z| =0{--}2 {kpc}, for 15 elements in...
  • Publication
    Chemical Cartography with APOGEE: Two-process Parameters and Residual Abundances for 288,789 Stars from Data Release 17
    Stellar abundance measurements are subject to systematic errors that induce extra scatter and artificial correlations in elemental abundance patterns. We derive...

    Chemical characterisation of the X-shooter Spectral Library (XSL): [Mg/Fe] and [Ca/Fe] abundances
    Context. The X-shooter Spectral Library (XSL) is a large empirical stellar library used as a benchmark for the development of stellar population models. The...
