Kepler rapid rotators and Ks-band excesses

Tens of thousands of rotation periods have been measured in the Kepler fields, including a substantial fraction of rapid rotators. We use Gaia parallaxes to distinguish...在开普勒天区（Kepler fields）中已测得数万余个自转周期，其中包含相当比例的快速自转天体（rapid rotators）。本研究利用盖亚（Gaia）视差（parallaxes）数据开展区分工作。
