Using a high resolution spectrum of the secondary star in the Low Mass
X-ray Binary (LMXB) A0620-00 we have derived the stellar parameters and
the veiling caused by the accretion disk in a consistent way. We have
used a χ 2 minimization procedure to explore a grid of
600000 synthetic spectra computed for a plausible range of both stellar
and veiling parameters. Assuming the best model parameters, we have
studied elemental abundances of Fe, Ca, Ti, Ni, Al, and obtained
abundance values close or slightly higher than solar. We have also
analyzed the Li abundance which is unusually high for a star of this
spectral type and relatively low mass.
