中文摘要：

利用中国南极洲昆仑站的小望远镜阵列得到的测光数据对食双星CSTAR083768进行了研究.相位弥散计算确定轨道周期P=0.384113d.2003版的Wilson-Devinney程序对光变曲线进行模拟表明：它是一颗W UMa双星系统,两颗子星都充满洛希瓣,相接度F=43.8%,轨道倾角i=64.563°,两子星的质量比M2/M1=0.485。

英文摘要：

By using the photometric data obtained from the Chinese Small Telescope Array at the Dome A, an eclip- sing binary, CSTAR083768, was analysed. By the Phase Dispersion Minimization method, the orbital period was determined and was 0. 384 113days. By using the Wilson-Devinney Code（2003）, the photometric solutions to the eclipsing binary were obtained. The photometric solution show that the CSTAR083768 is a W UMa eclipsing binary, both components filling its Roche lobe and its fill-factor being 43.8%. Its mass ratio （ M2/Ml ） is 0. 485 with an inclination of 64. 563.
