论文摘要
黯然失色的二进制系统中的第三个机构会导致（o）减去计算的（c）日食时期的定期周期性变化。从O-C数据很少检测到第四体。我们将新的离散卡方法（DCM）应用于黯淡的二进制XZ andromedae的O-C数据。这些数据包含至少十个宽轨道恒星（WOSS）的周期性特征。它们的轨道周期在1.6至91.7岁之间。由于在XZ的日食中没有观察到任何变化，并且在过去的127年中，所有这些涡流的轨道很可能是共同的平面。我们提供了有关专业和业余天文学家如何使用普通PC轻松重复我们DCM分析的所有阶段的详细说明，并将这种方法应用于其他黯淡的二进制文件的O-C数据。
A third body in an eclipsing binary system causes regular periodic changes in the observed (O) minus the computed (C) eclipse epochs. Fourth bodies are rarely detected from the O-C data. We apply the new Discrete Chi-square method (DCM) to the O-C data of the eclipsing binary XZ Andromedae. These data contain the periodic signatures of at least ten wide orbit stars (WOSs). Their orbital periods are between 1.6 and 91.7 years. since no changes have been observed in the eclipses of XZ And during the past 127 years, the orbits of all these WOSs are most probably co-planar. We give detailed instructions of how the professional and the amateur astronomers can easily repeat all stages of our DCM analysis with an ordinary PC, as well as apply this method to O-C data of other eclipsing binaries.
