J/A+AS/129/563 Abundances of HR 4487, 14 Hyd and 3 Cen A (Pintado+ 1998) ================================================================================ Elemental abundance analyses with Complejo Astronomico El Leoncito REOSC Echelle Sprectrograms. III. HR 4487, 14 Hydrae and 3 Centauri A Pintado O.I., Adelman S.J., Gulliver A.F. =1998A&AS..129..563P (SIMBAD/NED BibCode) ================================================================================ ADC_Keywords: Stars, peculiar ; Abundances, peculiar Keywords: stars: abundances - stars: chemically peculiar - stars: individual: HR 4487, 14 Hya, 3 Cen A 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.
