Membership and Dynamics of the Chamaeleon I star forming region with the Gaia-ESO Survey
The Gaia-ESO Survey (GES) will provide radial velocities, projected rotational velocity and stellar parameters of 10^5 Milky Way stars in the field and in clusters. One of the main goals of the survey is to investigate the formation and the evolution of young clusters, by the analysis of their internal kinematic. We will present the results obtained from the analysis of the GES observations of the young cluster Chamaeleon I. Specifically, we will present a new membership selection, the structural and dynamical properties of cluster, and we will discuss our results in the context of the current theoretical scenario on the early evolution of young cluster.
