The first CCD photometric analysis and modeling for short period eclipsing binary system 1SWASPJ210423.7+073140.4.

Abstract We present the first light curve analysis of the new eclipsing binary of WUMa type 1SWASP J2104. A detailed photometric analysis was carried out in VRI bands using the most recent version of Wilson–Devinney (WD) code. The absolute physical parameters of the system were obtained and the previously determined period was confirmed. The evolution state shows that the primary component is slightly evolved above the ZAMS track while the secondary is on TAMS track. Our results show that the spectral types of the primary and secondary stars of the studied system are K4 and K5, respectively. The distance to 1SWASP J2104 was calculated to be 307 ± 21pc.
