论文摘要
测量脱落二进制组（EBS）或行星系统中的一个组件之一的恒星旋转是一项艰巨的任务。难度主要是由于在相同的光曲线中分析的复杂性，来自恒星旋转的信号与恒星或子策略伴侣的过境信号（如棕色矮人或行星）混合在一起。有许多方法可以纠正光曲线的长期趋势。但是，校正通常会从穿越可见恒星磁盘和其他较弱的信号（如行星）的斑点中删除恒星旋转的信号。在这项工作中，我们提出了切割二进制（鼓声）的差异通量方法，以识别二进制传输的信号并将其从恒星旋转行星信号中解散。我们向Corot，Kepler，Kepler K2和Tess Missions的EBS提供了应用。我们还应用了我们的方法来模拟柏拉图任务的合成EB。我们的方法在确定恒星旋转周期的良好同意中，对于上一次太空任务的几乎观察到的目标，它对于未来的欧洲任务（例如，恒星的行星转移和振荡（Plato））自然是有用的。
Measuring the stellar rotation of one of the components in eclipsing binaries (EBs) or planetary systems is a challenging task. The difficulty is mainly due to the complexity of analyzing, in the same light curve, the signal from the stellar rotation mixed with the transit signal of a stellar or sub-stellar companion, like a brown dwarf or planet. There are many methods to correct the long-term trend of the light curve. However, the correction often erases the signal of the stellar rotation from spots crossing the visible stellar disk and other weaker signals like planets. In this work, we present the DiffeRencial flUx Method of cuTting Off biNariES (DRUM TONES) to identify the signal of the binary transits and disentangle it from stellar rotation planet signals. We present our technique with applications to EBs from CoRoT, Kepler, Kepler K2 and TESS missions. We also applied our method to simulated synthetic EB from the PLATO mission. Our method shows good agreement in the determination of stellar rotation periods for few observed targets from last space missions, as well it is naturally useful for future European missions, such as PLAnetary Transits and Oscillations of stars (PLATO).
