Near-Ultraviolet Observation of Four Bright MN Stars
Abstract
Near-ultraviolet spectra, obtained with the ESRO TD-1A/S59 experiment, of the four Mn stars β Tau, γ Crv, α And, and μ Lep and six normal stars are compared. The normal stars show good agreement with synthetic spectra. The Mn stars have spectra which become hotter at shorter wavelengths. They also show strong MnII lines and weak MgII lines. A time-variation for TiII λ 2828 was noted in γ Crv and α And.
