Activity and rotation of low mass stars in young open clusters

Abstract

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.
