摘要
我们展示了使用VLT/ flame对IC2602、星团、昴宿星团和后发星团进行的多目标光谱活动的第一批结果。我们分析了径向速度、旋转速度(v sin i)和Hα活性的数据。在这里，我们重点介绍了本研究在旋转制动和低质量恒星旋转活动关系背景下的三个方面。最后讨论了IC2602中源的集群隶属关系。
Activity and rotation of low mass stars in young open clusters
We present first results from a multi‐object spectroscopy campaign in IC2602, the Hyades, the Pleiades, and the Coma cluster using VLT/FLAMES. We analysed the data for radial velocity, rotational velocity (v sin i), and Hα‐activity. Here, we highlight three aspects of this study in the context of rotational braking and the rotation‐activity relationship among low mass stars. Finally we discuss the cluster membership of sources in IC2602.
