Scientific paper

The phase evolution of stars from Class 0/I protostars to Class III stars is hard to test due to biases in the population samples. Combining Chandra and Spitzer data allows us to identify and characterize populations of young stars still embedded in their birth clouds. We propose to observe a very young cluster IRAS 20050+2750 in which we have identified 240 members via mid-IR excesses including 84 protostars. The proposed 100 ks observation will allow us to identified the Class III component of this cluster. These data, along with unusually complete 24 micron data, will allow us to characterize the whole population of the cluster, including the X-rays flux of the protostars and the timescales involved in the evolution of the cluster and the optically thick disks.
