A spectroscopic study of some suspected chemically peculiar stars.
LEONE F. and CATANZARO G.
Abstract (from CDS):
Time-resolved spectra in the 410-700nm range have been obtained to investigate 10 stars which are classified as suspected chemically peculiar stars in The General Catalogue of Ap and Am stars by Renson et al. (1991A&AS...89..429R) or in the latest literature. Among the studied stars, HD 20629 presents metal abundances which are significantly different from main sequence star values and it should be classified as Silicon star. From the HeI587.6 nm line, we conclude that HD 35575 is a helium weak star. Because of the found radial velocity variability and the derived abundances, the periodic photometric variable HD 38602 could be an ellipsoidal variable.
