Abstract

New photoelectric B and V band light curves of the contact binary ET Leonis were studied to determine the physical parameters of the system. The observations were obtained at TUBiTAK National Observatory (TUG) on consecutive nights in March 2003. The light curves exhibit the so-called O'Connell effect with the level of the second maxima being higher than that of the first in both bands. The amplitudes of the light curves are very small, indicating a relatively low orbital inclination angle. The new light curves and the radial velocity curve were analysed simultaneously using the last version of the Wilson-Devinney Code (WD-2003). The analysis yields a W-type W UMa system viewed at a very low orbital inclination angle.
