A X-ray view of the young star population in CMa R1
Abstract
In previous works we studied the star formation scenario in the molecular cloud Canis Major R1 (CMa R1), revealing the existence of young stellar groups near the Be stars Z CMa and GU CMa. Using data from the ROSAT X-ray satellite, Gregorio-Hetem et al. (2009) - GH2009 - discovered in this region young stellar objects (YSOs) mainly grouped in two clusters of different ages. In order to investigate the nature of these objects and to test a possible scenario of sequential star formation in this region, four fields (each 30' diameter, with some overlap - Figure 1) have been observed with the XMM-Newton satellite that has a sensitivity about 10 times better than ROSAT.
