Oxygen abundances in early B-stars.

KOROTIN S.A., ANDRIEVSKY S.M. and LUCK R.E.

Abstract (from CDS):

Kurucz atmospheric models and a modified version of the MULTI code are applied in a NLTE investigation of the OII spectrum. It is shown that previously performed analyses based on the use of lightly line-blanketed Gold models give results that are in variance with those based on the use of the more heavily blanketed Kurucz models. One result of our calculations is a number of useful relationships between the NLTE oxygen abundance, line equivalent width, and stellar atmospheric parameters. A NLTE analysis of O II lines in a sample of hot main sequence B stars has been performed. The derived oxygen abundances for the program stars appear to be subsolar. A brief comparison is presented between the oxygen abundance in B stars and other related stellar types.
