SUMMARY OF SEQUENCE NUMBER 200059

Title: HARD X-RAY SEARCH FROM CLASS 0 PROTOSTARS

Observer: TSUBOI

Subject Category: Normal Stars and WD

Seq: 200059 ObsId: 00634

Long-term Plan bin: 26-Dec-1999

ABSTRACT

We propose to observe the Orion Molecular Clouds, OMC 2 and OMC 3, with the ACIS-I instrument. With ASCA, these regions are found to exhibit hard X-ray emissions, possiblly from embedded Class 0 and Class I protostars. Our goal is to investigate; (1) when a star begins to emit X-rays, (2) what is the difference in X-rays (spectrum and time variability) between Class 0 and Class I, and the other phases of star formation (ClassII, III), and (3) what is the X-ray emission mechanism in the protostar phase.
