| 摘 要： | 本文给出了首次食双星V375 Cas的BV两色光电测光资料和新的历元,并用Wilson-Devinney综合光变曲线方法取得测光解。结果表明:V375 Cas是一个类似RZ Dra的早型半相接双星系统,小质量子星充满了临界等位面,而大质量子星几乎充满了临界等位面,此星对于了解早型密近双星的演化是很有意义的。

| Abstract: | Approximately 604 photoelectric BV observations of the eclipsing binary V375 Cas were obtained at Beijing Observatory from August to November in 1982. Photometric solution was carried out with "Wilson-Devinney program for the BV light curves of V375 Cas. The system is found to be semi detached binary where the less massive component fills its Roche surface, whereas the other component is almost contact to its Roche surface. It is very similar to EZ Dra. The system is very interesting and important to understand the evolution of the close binary systems. |
