Radial and projected rotational velocities in NGC2264
Abstract
Radial velocity (RV) measurements are a powerful tool for investigating kinematic substructure in young star forming regions. We present RV's for 610 stars in the young nearby star forming region NGC2264. These cover a magnitude range of 12.5 < I < 18.5 and have been derived from R=16200 spectra obtained using the Giraffe spectrograph at the VLT, Chile. We explore the likelihood of kinematic substructure within the cluster and compare this with the already-known spatial sub-groups. The distribution of RVs is non-Gaussian, with several separate RV sub-groups. We also present projected equatorial velocities for stars in NGC2264.
