Elemental abundance analyses with DAO spectrograms - IX. The mettalic-lined stars 15 Vulpeculae and 32 Aquarii.
Abstract
Elemental abundance analyses of the sharp-lined bright Am stars 15 Vul and 32 Aqr are presented. The values derived using fine analysis techniques are found via the stellar parameters, effective temperature, and surface gravity, determined with optical-region spectrophotometry and Balmer line profiles as well as with the procedures of Moon & Dworetsky (1985) and of Lane & Lester (1980, 1987). The latter star is a more extreme Am star than the former. Possible ways to improve these analyses are also discussed.
