This complex is situated 300 pc above the Galactic plane, and appears to be part of a 270 pc diameter ring of atomic and molecular clouds expanding at 22 km/s (Megeath et al (2003) . It appears that two modes of triggered star formation are at work here: an initial supernova to trigger the ring complex and the initial O stars and the subsequent triggering of low mass star formation by photoevaporation driven molecular core compression. To get a complete census of the Young Stellar Population, we use Chandra ACIS for 100 ksec coupled with data from 2MASS and Spitzer. The Master Xray catalog now has 446 sources, 145 soft, 213 medium, 154 hard, 303 broad. We present an X-ray spectral analysis of the Xray sorces with IR counterparts. We present the Xray luminosity function, its completeness and number of missing sources and their energy and energy distribution. We present the spatial distribution of CI v. CII v. CIII to study the progress of star formation. |
