Abundances of selected elements in five oxygen-poor stars in omega Centauri.

ZUCKER D., WALLERSTEIN G. and BROWN J.A.

Abstract (from CDS):

We have derived abundances or upper limits for Fe, O, Na, Al, Sc, and Eu in five oxygen-poor red giants in Omega Centauri, a globular cluster which displays a metallicity range of some 1.5 dex. All of the stars show large Al excesses and slight Sc excesses, and all but one reveal an excess of Na. We find either solar or slightly deficient Eu abundances in these stars, in agreement with other recent results. We have also used spectral synthesis to derive 12C/13C ratios which are similar to ratios obtianed for oxygen-rich stars in Omega Centauri and in other globular clusters.
