Elemental abundance analyses with Complejo Astronomico El Leoncito REOSC echelle spectrograms. II. µ Leporis, 7 Sextantis, HR 4817, and 28 Herculis.

Abstract (from CDS):

Elemental abundances are derived for four sharp-lined stars, the Mercury-Manganese stars µ Lep, HR 4817, and 28 Her, and 7 Sex, a Population I star with Population II space motions, using REOSC echelle spectrograms obtained at CASLEO to extend previous studies. Comparisons with published equivalent widths indicate that the CASLEO scale is marginally larger than those of DAO Reticon and KPNO CCD spectra. The CASLEO spectrograms have improved the quality of the abundance determinations. New abundances are found for a few elements.
