Abstract (from CDS):

Fine analysis of the B and A stars, gamma Geminorum, 7 Sextantis, HR 4817, and HR 5780 are extended using additional spectrograms obtained at the KPNO coude feed telescpe with a TI CCD, camera 5, and grating A. In addition HD 60825, a star with colors similar to FHB A stars, but was found to be a Population I star is studied. ATLAS9 model atmospheres are used in these new analyses. HD 60825 as is gamma Gem is a sharp-lined early A star with nearly solar derived abundances. HR 5780 and 7 Sex are also examples of stars which for the most part have solar abuandances. The newly derived abundances for HR 4817 reveal important differences with respect to 53 Tau, a somewhat similar peculiar HgMn star.
