Elemental abundance analyses with Complejo Astronómico El Leoncito REOSC echelle spectrograms. I. κ Cancri, HR 7245, and ξ Octantis

Abstract

Elemental abundances are derived for three sharp-lined stars Cnc, HR 7245, and Oct using REOSC echelle spectrograms obtained at CASLEO. Comparisons are made with published equivalent widths. The derived abundances for Cnc and Oct are slightly larger than those obtained with other high dispersion spectrographs. HR 7245 exhibits a pattern of abundance anomalies similar to other Mercury-Manganese stars. The spectra of the two HgMn stars in the 4640 5100 region exhibit an interesting and useful variety of lines which can be used to supplement analyses of the photographic region.
