Abstract:
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.
Description:
The core of the Serpens cloud was observed with Chandra starting at
21:43 UT on June 19, 2004. The observation lasted for 91.4ks
(although the scheduled duration was 100ks).
