HARD X-RAY EMISSION FROM YOUNG EMBEDDED CLUSTER NGC 2264
ABSTRACT
Recent molecular and NIR observations of relatively large regions of sky revealed that the dense and massive clusters are the units of star formation in a giant molecular cloud, which is usually associated with OB association. They appear to be birthplace of most OB stars, and the cluster-mode star formation is the dominat mechanism to form most stars in OB associations. We proposed the hard X-ray observations of the embedded population of PMS stars and protostars in the NGC 2264. NGC 2264 is the young ( < 5 Myr ) and rich cluster in the Mon OB1 association. Comparison with X-ray emission from low mass star forming region will provide new insights into the embedded cluster formation and stellar birth in a giant molecular cloud.
