发现深的低质量比过接触双星GSC 03517-00663
Discovery of a deep, low mass ratio overcontact binary GSC 03517-00663
摘要：
在观测耀变体时，我们发现了一个新的食双星GSC 03517-00663。GSC 03517-00663的光变曲线是典型的EW型光变曲线。利用山东大学威海天文台1米望远镜的观测资料，测定了完整的VRI光变曲线。然后，我们用W-D程序分析了多重光变曲线。发现GSC 03517-00663具有质量比q=0.164和接触度f= 69.2%。GSC 03517-00663是一个深、低质量比的过接触双星。GSC 03517-00663的光变曲线显示出强烈的O 'Connell效应，这是通过在次级组分上采用暗点来解释的。
英文摘要：
When observing the blazars, we identified a new eclipsing binary GSC 03517-00663. The light curves of GSC 03517-00663 are typical EW-type light curves. Based on the observation using the 1m telescope at Weihai Observatory of Shandong University, complete VRI light curves were determined. Then, we analyzed the multiple light curves using the W-D program. It is found that GSC 03517-00663 has a mass ratio of q=0.164 and a contact degree of f=69.2%. GSC 03517-00663 is a deep, low mass ratio overcontact binary. The light curves of GSC 03517-00663 show strong O'Connell effect, it was explained by employing a dark spot on the secondary component.
