Abstract We present a new multicolor CCD photometry and light curve analysis of two eclipsing binary systems, 1SWASP J133417.80 + 394314.4 and V2790 Orion. The photometric solutions for both binaries were carried out using the updated version of the Wilson– Devinney code. The results showed that first systems is A- type W UMa with mass ratios q = 0.158 while the second system is W- type with q = 3.2. The systems show over contact configuration with fill-out factors of f = 43% and 14% respectively. We calculated the orbital and absolute physical parameters for both systems and investigated their evolutionary state.

两个 WUMaBinaries 的新 CCD 光度测量和光曲线分析：1SWASP J133417.80+394314.4 和 V2790 Orion

摘要 我们提出了两个食双星系统 1SWASP J133417.80 + 394314.4 和 V2790 Orion 的新多色 CCD 光度测量和光变曲线分析。使用更新版本的 Wilson-Devinney 代码对两个二进制文件进行了光度测量解决方案。结果表明，第一个系统是A-型W UMa，质量比q = 0.158，而第二个系统是W-型，质量比q = 3.2。系统显示过接触配置，填充因子分别为 f = 43% 和 14%。我们计算了两个系统的轨道和绝对物理参数，并研究了它们的进化状态。
