Abstract:
Ussing CASLEO echelle spectrograms, elemental abundances are derived
for the sharp-lined non-magnetic CP stars HR 4487, 14 Hya and 3 Cen A.
The first two stars are members of the Mercury-Manganese subgroup and
have abundances which are similar to other such peculiar stars. The
third is a hotter related star. The detection of Mn II lines in its
spectrum adds to this relationship.
