本文介绍了 YY Eridani 在 B 和 V 波段的完整光变曲线。光变曲线似乎与 Max 有明显的不对称性。我比马克斯更聪明。二.使用最新版本的 Wilson-Devinney 光曲线合成程序，我们根据 YY Eri 的新光曲线计算了光度解。目前的解决方案表明，YY Eri 是 W 亚型接触二元。光变曲线的不对称性可以通过主要或次要组件上存在黑点来解释。
Complete light curves in B and V bands for YY Eridani are presented in this paper. The light curves appear to have a marked asymmetry with Max. I brighter than Max. II. Using the latest version of the Wilson-Devinney light curve synthesis program, we have computed photometric solutions from the new light curves of YY Eri. The present solutions reveal that YY Eri is a W subtype contact binary. The asymmetries of the light curves are explained by the presence of dark spot on the primary or secondary component.
