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 with prior investigators, we find that the O abundance from the triplet is about 0.53 dex higher than is typically found from other means such as the [O I] $lambda$6300 {AA} line or the UV
