Oxygen abundances in low- and high-alpha field halo stars and the discovery of two field stars born in globular clusters
I. Ramirez, J. Melendez, J. Chaname
Oxygen abundances of 67 dwarf stars in the metallicity range -1.6<[Fe/H]<-0.4 are derived from a non-LTE analysis of the 777 nm O I triplet lines. These stars have precise atmosphe…
