Rotation periods of active Kepler stars

We present rotation periods for thousands of active stars in the Kepler field derived from Q3 data. In most cases a second period close to the rotation period was detected,...本研究报道了基于开普勒观测天区（Kepler field）第三季度（Q3）观测数据推导得到的数千颗活动恒星的自转周期。多数情况下，可检测到一个与该自转周期相近的次级周期……
