Study of Kepler's FGKM stars

While stellar rotation periods P_rot_ may be measured from broad-band photometry, the photometric modulation becomes harder to detect for slower rotators, which could bias...尽管可通过宽带测光法（broad-band photometry）测定恒星自转周期P_rot，但慢速旋转恒星的光度调制（photometric modulation）更难被探测，这可能会引入观测偏差……
