Abstract:
Elemental abundances analyses are performed for the Mercury-Manganese
stars υ Her, φ Her, and HR 7018 consistent with previous
studies of this series using spectrograms obtained with Reticon and
CCD detectors. Comparisons of the first two analyses with those
performed using coadded photographic plates show the general
consistency of the derived elemental abundances. For υ Her and
for φ Her, abundances were newly found for O, and for Al, V, Zn,
and Ce, respectively. HR 7018 is discovered to be a single-lined
spectroscopic binary. Its Sc abundance is the smallest of any class
member with derived abundances and its Sr abundance the largest of any
known HgMn star. A correlation analysis of the most complete abundance
sets for 20 HgMn stars shows that the abundances of some elements are
correlated with one another and some are functions of the stellar
effective temperature.
