Abstract

We have obtained the first UBVR photoelectric light curves for a recently discovered eclipsing binary with a period of 9.33d and an appreciable eccentricity (e=0.08). We have used these data to determine the photometric elements of the system for a model with two spherical stars with linear limb darkening. The high accuracy of the observations enabled determination of the absolute parameters of the components using available calibrations. The masses of the components are 1.28 and 1.08M_{sun}_, and their ages are two billion years. The present orientation of the orbital ellipse is unfavorable for studies of the apsidal rotation, which is essentially due to relativistic effects.
