X-RAY OBSERVATIONS OF CLASS 0 OBJECTS
ABSTRACT
It is very important to observe star forming region in the hard X-rays because the hard X-rays are transparent even in dark cloud. Moreover, X-ray observation is the only tool to observe activities on the stellar surface of protostars. We have detected X-rays from some protostar candidates located in the Rho-Oph and R CrA clouds. One hard source shows a sinusoidal variation which suggests rapid rotation of the protostar. However, the sample is limited in order to investigate the mechanism of X-ray emission of protostars, for example, the relation between the X-ray activities and the rotation. Thus, we propose observation of class 0 objects IRAS 03282+3035 and IRAS 03301+3057 located in the Perseus molecular complex.
