Scientific paper

In many Type II supernovae (SNe), and some SN Ib/c, the interaction between the SN shock and the circumstellar material shed by the progenitor star creates a strong reverse shock that becomes extremely luminous in X-rays (> 10^39 erg/sec, 0.1-2.4 keV). The X-ray luminosity can be reasonably predicted by detecting the accompanying electron synchrotron radio emissions from the shocked regions. We propose AXAF ToO observations of selected categories of SNe to substantially increase the number of X-ray detections (currently at nine). Combined X-ray and radio observations will test theories of the shock mechanism and provide information on the SN progenitor. In addition X-ray spectra of the brighter SNe will constrain the physical properties of the reverse shock region and the SN ejecta.
