    Chemical abundances of 1111 FGK stars from the HARPS GTO planet search program. IV. Carbon and C/O ratios for Galactic stellar populations and planet hosts
    Context. To understand the formation and composition of planetary systems, it is essential to have insights into the chemical composition of their host stars...
  • Publication
    Chemical abundances of 451 stars from the HARPS GTO planet search program. Thin disc, thick disc, and planets
    We present a uniform study of the chemical abundances of 12 elements (Si, Ca, Sc, Ti, V, Cr, Mn, Co, Ni, Na, Mg, and Al) derived from the spectra of 451 stars...
  • Publication
    Chemical abundances of distant extremely metal-poor unevolved stars
    Context. The old Galactic halo stars hold the fossil record of the interstellar medium chemical composition at the time of their formation. Most of the stars...
  • Publication
    Chemical abundances of late-type pre-main sequence stars in the σ Orionis cluster
    Context: The young σ Orionis cluster is an important location for studying the formation and evolution of stars, brown dwarfs, and planetary-mass objects. Its...

    Chemical Abundances of M-dwarfs from the APOGEE Survey. I. The Exoplanet Hosting Stars Kepler-138 and Kepler-186
    We report the first detailed chemical abundance analysis of the exoplanet-hosting M-dwarf stars Kepler-138 and Kepler-186 from the analysis of high-resolution...
  • Publication
    Chemical Abundances of Main-sequence, Turnoff, Subgiant, and Red Giant Stars from APOGEE Spectra. I. Signatures of Diffusion in the Open Cluster M67
    Detailed chemical abundance distributions for 14 elements are derived for eight high-probability stellar members of the solar metallicity old open cluster M67...
  • Publication
    Chemical Abundances of Main-sequence, Turnoff, Subgiant, and Red Giant Stars from APOGEE Spectra. II. Atomic Diffusion in M67 Stars
    Chemical abundances for 15 elements (C, N, O, Na, Mg, Al, Si, K, Ca, Ti, V, Cr, Mn, Fe, and Ni) are presented for 83 stellar members of the 4 Gyr old solar...
  • Publication
    Chemical Abundances of Neutron-capture Elements in Exoplanet-hosting Stars
    To understand the formation and composition of planetary systems it is important to study their host stars composition since both are formed in the same stellar...
