Scientific paper

An optical variability study of the "benchmark" star forming region NGC2264, observed with CoRoT, indicates that the cluster is more extended than currently believed. We propose to observe with EPIC two fields in the outskirts of NGC2264, each for 50ks. We want to: 1) confirm by means of X-ray detection the existence of a spatially extended population; 2) establish the star formation history of the region, e.g. whether the clustered and dispersed populations originated from the same or distinct formation events; 3) determine whether mass segregation affects NGC2264, thus compromising current determinations of the Initial Mass Function; 4) derive disk frequencies throughout the cluster and in sub-regions with different stellar densities and UV-radiation fields.
