    Oxygen Abundances in Unevolved Metal-poor Stars from Near-Ultraviolet OH Lines
    We have performed a detailed oxygen abundance analysis of 23 metal-poor (-3.0 [Fe/H] -0.3) unevolved halo stars and one giant through the OH bands in the near...

    Oxygen in the Very Early Galaxy
    Oxygen abundances in a sample of ultra-metal-poor subdwarfs have been derived from measurements of the oxygen triplet at 7771-5 Å and OH lines in the near-UV...

    Oxygen Isotopic Ratios in Cool R Coronae Borealis Stars
    We investigate the relationship between R Coronae Borealis (RCB) stars and hydrogen-deficient carbon (HdC) stars by measuring precise 16O/18O ratios for five...

    Oxygen, sulfur, and iron radial abundance gradients of classical Cepheids across the Galactic thin disk★★★
    Context. Classical Cepheids (CCs) are solid distance indicators and tracers of young stellar populations. Dating back to the beginning of the 20th century, they...
