To study the properties of X-ray emission from young stellar objects (YSOs) through their evolution from Class I to Class III and determine whether Class 0 protostars emit X-rays. A deep Chandra X-ray observation of the Serpens star-forming region was obtained. The Serpens Cloud Core is ideally suited for this type of investigation, being populated by a dense and extremely young cluster whose members are found in all evolutionary stages, including six well-studied Class 0 sources.
Cone search capability for table J/A+A/463/275/table5 (X-ray sources detected with PWDETECT in the Chandra observation of the Serpens star forming region.)
Cone search capability for table J/A+A/463/275/table6 (The cross-identification of the sources below was obtained from the Simbad database, with a search radius of 5 arcsec.)
