Subject: SUPERNOVA REMNANTS AND GALACTIC DIFFUSE EMISSION
OBSERVATIONS OF SN1993J
ABSTRACT
SN 1993J is one of five recent supernova explosions (SNe) detected in X-rays. It is observationally unprecedented, in that it is the only SNe detected in the radio and in X-rays within a week of the explosion, and whose X-ray light curve and spectral evolution have been carefully measured for over one year. Recently, the X-ray light curves shows increase and decrease whose origin is still not known. This time variability implies many important features, such as the expansion of the shock wave, and as circumstellar density profile. Thus, continuous monitoring is urged. Furthermore, we also expect to detect emission from a pulsar, if it is as bright as Crab pulsar.
