Subject: STARS
STUDY OF X-RAY EMISSION FROM CLASS 0 PROTOSTAR
ABSTRACT
X-ray observation of class 0 protostar, L1157 is proposed. ASCA detected X-ray emission from Class I protostars for the first time. The origin of the X-ray emission from protostars is very unclear, however, the X-ray emission gave us very impotant information about star formation, for example about rotaion, and magnetic field. The proposed taeget L1157 at a distance of 440pc has well-collimated bipolar outflows which cause strong shock-heating of the ambient gas.
