Contribution
It presents new spectroscopic data on low-mass stars in several young clusters, focusing on rotation, activity, and membership analysis, which advances understanding of stellar evolution.
Findings
Insights into rotational braking mechanisms.
Correlation between rotation and H-alpha activity.
Refined cluster membership assessments.
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, and H-alpha 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.
