Spectral classification from the ultraviolet line features of S2/68 spectra. III. Early A-type stars.
Abstract
This paper concerns the classification of more than 600 A04A3-A4) spectra obtained with the sky survey telescope (S2/68) mounted on the TDi satellite. As in the two previous papers of this series, a statistical study of the spectra is made to establish ultraviolet classification criteria. The scheme thus established permits separation of 14% of the stars showing an abnormal ultraviolet spectrum. Key words: classification - ultraviolet - early A stars
