Scientific paper

We propose two 100-ksec ACIS-I observations of the extremely young, dense, massive star-forming region DR21 in the Cygnus X complex. We aim at studying how strongly the presence of a cluster of very young massive stars influences the formation and early evolution of lower-mass cluster stars (efficiently selected from ACIS X-ray images), and their circumstellar environment (already being studied with Spitzer data). The DR21 region and the nearby cluster DB16 are a very good laboratory for an observational study of sequential/triggered star formation, to be compared with existing theoretical pictures. We will perform X-ray spectral and variability analysis for the most intense sources. We will also search for diffuse hot gas, found in star-forming regions with similar chaaracteristics.
