| 英文摘要 | When observing blazars, we identified a new eclipsing binary named GSC 03517-00663. The light curves of GSC 03517-00663 are typical of EW-type light curves. Based on the observation using the 1 m telescope at the Weihai Observatory of Shandong University, complete VRI light curves were determined. Then, we analyzed the multiple light curves using the Wilson-Devinney program. It was found that GSC 03517-00663 has a mass ratio of q = 0.164 and a degree of contact of f = 69.2 %. GSC 03517-00663 is a deep, low mass ratio overcontact binary. The light curves of GSC 03517-00663 show a strong O'Connell effect, which was explained by employing a dark spot on the secondary component. |
