Abstract A lot of data in time domain were obtained by the Kepler mission, including many contact binaries. Long-term observation lets us obtain more information about the short time scale variation in their light curves or in their orbital periods. Unfortunately, the exposure time is too long (most of them are 30 minutes). Hence, many variations in light curves are smoothed. To avoid this problem, we analyzed some Kepler contact systems with both long-cadence mode and short-cadence mode data. Using the latest version of the Wilson-Devinney code, we obtained the physical parameters of a batch of contact binaries and find out four targets(KIC 5123176, KIC 5296877, KIC 8496820, KIC 9776718) have low mass ratios (q

五个开普勒接触双星的光度学研究

摘要 开普勒任务获得了大量时域数据，包括许多接触二进制文件。长期观察让我们获得更多关于光变曲线或轨道周期短时间尺度变化的信息。可惜曝光时间太长（大部分是30分钟）。因此，光变曲线的许多变化都被平滑了。为了避免这个问题，我们分析了一些具有长节奏模式和短节奏模式数据的开普勒接触系统。使用最新版本的 Wilson-Devinney 代码，我们获得了一批接触双星的物理参数，并找出了四个具有低质量比（q
