Abstract
A self-consistent physical model, described in an earlier paper by Lin nell & Hubeny, has permitted fits of synthetic spectra to observed spe ctra of EE Pegasi. The synthetic spectra determine abundances for iron , calcium, and silicon. The same model has been the basis of an optimi zed light synthesis solution of an accurate light curve by Ebbighausen . The solution, requiring use of a model atmospheres option to represe nt the component star radiative properties, agrees with the standard s olution by Lacy & Popper. The derived component parameters place them on an isochrone, determine a compositional Z, and are in accordance wi th evolution tracks by Schaller et al. The model is not restricted to systems with small distortion.
