SUMMARY OF SEQUENCE NUMBER 200060
Title: RESOLVING EMBEDDED X-RAY OBJECTS IN RHO OPH CLOUD CORE
Observer: TSUBOI
Subject Category: Normal Stars and WD
Seq: 200060 ObsId: 00635
Long-term Plan bin: 10-Apr-2000
ABSTRACT
With the ASCA observations of the Rho Oph dark cloud, we found variable hard X-ray emission from Class I sources. A Class I (EL29) shows a flare like TTSs, other (WL6) varies sinusoidally, suggesting rotation period, and the other (YLW15) exhibit quasi-periodic flares, suggestive for the star-disk magnetic connection. Non X-ray emitting Class I is also found. Our proposal is, with no source confusion problem, to confirm these variety of X-ray activity, to search for X-rays from other Class Is, as well as new X-ray emitting young stellar objects, using ACIS with the high spatial resolution up to 10 keV energy. Together with the radio search of bipolar structure, and comparison of TTSs, our goal is to give strong constrain on the evolution and structure of protostars.
