Abstract
•The system is an overcontact binary that both stars fill its Roche lobe.•The spectral types of the primary and secondary stars are G1 and G2, respectively.•The primary component is above the ZAMS track and the secondary one is close to the TAMS track.
We present a CCD photometric study for the newly discovered short period eclipsing binary 1SWASP J210318.76+021002.2 using BVRI observations carried out on 8 Sept. 2013 using Kottamia optical telescope at NRIAG, Egypt. The observed light curves were analyzed using Willson–Devinney code. The accepted solution shows that the primary star is more massive and hotter than the secondary with about 72K and has a hot spot with temperature factor about 1.25. The system is at a distance of 710±29 pc. Evolutionary state of the system is investigated using stellar models.
