Elemental abundances of the B and A stars. III - Gamma Geminorum, HR 1397, HR 2154, HD 60825 and 7 Sextantis

Using ATLAS9 model atmospheres and additional spectroscopic data from the Kitt Peak coude-feed telescope obtained with a 3000-pixel-long CCD, camera 5, and grating A, we extend fine analyses of the B and A stars, Gamma Gem, HD 60825, and 7 Sex. In addition, we study two moderately sharp-lined middle...

Zusammenfassung:Using ATLAS9 model atmospheres and additional spectroscopic data from the Kitt Peak coude-feed telescope obtained with a 3000-pixel-long CCD, camera 5, and grating A, we extend fine analyses of the B and A stars, Gamma Gem, HD 60825, and 7 Sex. In addition, we study two moderately sharp-lined middle B stars, HR 1397 and 2154, whose elemental abundances we find to be generally within the range of values seen for superficially normal, main-sequence stars of similar temperatures.
