    Oxygen abundances derived in unevolved very metal-poor stars
    Oxygen abundances have been derived in a sample of very metal-poor stars from observations of the Oi triplet at /λλ 7771-5 Å and OH lines in the near UV. Iron...

    Oxygen abundances in F-type stars of the Hyades and the Ursa Major group
    We have derived the oxygen abundances of 50 F-type main-sequence stars, belonging to the Hyades open cluster, the Ursa Major group, and the field, using an NLTE...

    Oxygen abundances in G- and F-type stars from HARPS. Comparison of [OI] 6300 Å and OI 6158 Å
    Aims: We present a detailed and uniform study of oxygen abundance from two different oxygen lines at 6158 Å and 6300 Å in a large sample of solar-type stars...

    Oxygen Abundances in Metal Poor Subgiant Stars from the O I Triplet
    This paper examines the oxygen abundance of 24 main-sequence turn-off and subgiant stars through the permitted O I triplet near $lambda$7774 {AA}. In agreement...
  • Publication
    Oxygen Abundances in Nearby FGK Stars and the Galactic Chemical Evolution of the Local Disk and Halo
    Atmospheric parameters and oxygen abundances of 825 nearby FGK stars are derived using high-quality spectra and a non-local thermodynamic equilibrium analysis...

    Oxygen abundances in nearby stars. Clues to the formation and evolution of the Galactic disk
    The abundances of iron and oxygen are homogeneously determined in a sample of 523 nearby (d 5500 K and [Fe/H] -0.3, we find no obvious indication of a sudden...
  • Publication
    Oxygen abundances in planet-harbouring stars. Comparison of different abundance indicators
    We present a detailed and uniform study of oxygen abundances in 155 solar type stars, 96 of which are planet hosts and 59 of which form part of a volume-limited...

    Oxygen abundances in unevolved metal-poor stars - Interpretation and consequences
    The oxygen abundance has been determined by analysis of the O I infrared triplet in 30 unevolved field stars of metallicities in the range Fe/H abundance ratio...
