Abstract

When observing the transiting extrasolar planets, we found a new eclipsing binary named GSC 02265-01456. The V and R (c) observations were carried out for this binary. The photometric light curves of the two bands were simultaneously analyzed using the W-D code. The solutions show that GSC 02265-01456 is an extremely low mass ratio (q=0.087) overcontact binary system with a contact degree of f=82.5%. The difference between the two maxima of the light curve can be explained by a dark spot on the primary component.
