Abstract

Using a high resolution spectrum of the secondary star in the black hole binary A0620-00, we have derived the stellar parameters and veiling caused by the accretion disk in a consistent way. We have used a chi^2 minimization procedure to explore a grid of 800 000 LTE synthetic spectra computed for a plausible range of both stellar and veiling parameters. Adopting the best model parameters found, we have determined atmospheric abundances of Fe, Ca, Ti, Ni and Al. The Fe abundance of the star is [Fe/H]=0.14 +- 0.20. Except for Ca, we found the other elements moderately over-abundant as compared with stars in the solar neighborhood of similar iron content. Taking into account the small orbital separation, the mass transfer rate and the mass of the convection zone of the secondary star, a comparison with element yields in supernova explosion models suggests a possible explosive event with a mass cut comparable to the current mass of the compact object. We have also analyzed the Li abundance, which is unusually high for a star of this spectral type and relatively low mass., Comment: 32 pages, 5 tables and 11 figures, uses rotate.sty

Abstract

We report the results of a non-LTE Fe, O and Mg abundance analysis of the carbon-nitrogen-rich ultra-metal-poor giants CS29498--043 and CS22949--037. The abundance of oxygen has been derived from measurements of the oxygen triplet at 7771-5 A in high resolution spectra obtained with KeckI/HIRES and the forbidden line [OI] 6300 A detected in the TNG/SARG spectra of CS29498-043. Detailed non-LTE analysis of Fe lines has provided reliable stellar parameters which, however, do not resolve the oxygen abundance conflict as derived from the OI 7771-5 A triplet and the [OI] 6300 A forbidden lines. We obtained the following oxygen abundance: for CS22949-037 [O/Fe] =3.13, 1.95; and for CS29498-043; [O/Fe]=3.02, 2.49, based on the OI 7771-5 A triplet and the [OI] 6300 A forbidden line, respectively. A similar conflict appears to exist between the forbidden resonance line MgI 4571 A and several subordinate lines, such as MgI 5172 and 5183 A. Our analysis demonstrates the failure of standard plane--parallel atmosphere models to describe the physical conditions in the line-forming regions of these ultra-metal-poor giants., Comment: 16 pages, 15 figures, accepted by Astronomy and Astrophysics
