Models of Activity Cycles of Chromospherically-Active Binary Stars

现在人们认为，许多表面温度与太阳相似或更低的恒星，其磁场活动周期与太阳的11年周期相似。其中一组恒星是所谓的RS CVn恒星，其活跃区域被认为与凉爽的圆形星斑区域有关。首席研究员（PI）建议使用档案和新获得的光度数据来研究RS CVn的食星。目的是确定这些恒星活动区域的大小和位置的长期趋势是否会揭示类似太阳周期的磁活动周期。此外，PI还建议确定恒星斑点区域相对于光球的温度。

It is now believed that many stars with surface temperatures like the sun's and less have magnetic activity cycles similar to the 11-year cycle of the sun. One group of such stars are the so-called RS CVn stars, whose active regions are thought to be associated with cool, circular starspot regions. The Principal Investigator (PI) proposes to use archival and newly obtained photometric data for the investigation of eclipsing RS CVn stars. The goal is to determine whether the long-term trends in sizes and locations of the active regions of these stars will reveal magnetic activity cycles similar to the solar cycle. In addition, the PI proposes to determine the temperature of the stars' spotted regions relative to their photospheres.
