Photometric light curve analysis of three overcontact binary systems: ATO J255.8159+16.8821, CRTS J034336.4+264312, and NSVS 2669503

Abstract Multi-band photometric observations of three contact binaries (ATO J255.8159+16.8821, CRTS J034336.4+264312, and NSVS 2669503) were carried out using the 1.88 m telescope at the Kottamia Astronomical Observatory (KAO) in Egypt. New times of minima for all three systems have been calculated....
