In the present paper, we obtained the first orbital solution for the newly discovered W UMa systems: GSC 3983-0544 and GSC 4502-1040. We used the most recent version of the Wilson-Devinney code to model the light curves of the two systems. The spectral type of the components of the two systems was adopted and the accepted solutions revealed some absolute parameters, which enable us to draw a preliminary picture of their evolutionary status.

两个 W UMa 系统的光度研究

在本文中，我们获得了新发现的 W UMa 系统的第一个轨道解：GSC 3983-0544 和 GSC 4502-1040。我们使用最新版本的 Wilson-Devinney 代码对两个系统的光变曲线进行建模。采用了两个系统组件的光谱类型，并且公认的解决方案揭示了一些绝对参数，这使我们能够初步了解它们的进化状态。
