Elemental abundance analyses with DAO spectrograms - XI. The early B stars gamma Pegasi and IOTA Herculis.
This paper presents LTE analyses of two sharp-lined early B stars, γ Pegasi and ι Herculis, based on co-added IIaO and Reticon 2.4 Å spectrograms of the photographic region. Most of the derived abundances are close to solar. Both stars have definite microturbulences which probably are related to the instability of their photo spheres.
