Chemical Abundances in the Secondary Star in the Black Hole Binary A0620–00

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 super(2) minimization procedure to explore a grid of 800,000 LTE synthetic spectra compute...
