Scientific paper

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