Abstract
We present the photometric study of an interesting target in the COROT exoplanet database, COROT 310266512. Its light curve shows primary, secondary, and tertiary eclipses. The primary and secondary eclipses have the same orbital period, 7.42 days, and the tertiary eclipse has an orbital period of 3.27 days. The properties of the light curve indicate that this multiple-eclipse light curve corresponds to two physically separate systems. The primary and secondary eclipses belong to a binary system, and the tertiary eclipse belongs to the other system. The tertiary eclipse has a flat part inside the eclipse which is about half the duration of the eclipse. The system of tertiary eclipse consists of two objects; one is smaller than another by a factor of 0.13–0.28 in radius, derived from the JKTEBOP code. The smaller object could be a giant planet or a dwarf star. Two of the tertiary eclipses fall within a primary eclipse and a secondary eclipse.
