Scientific paper

The X-ray emission from core-collapse SNe comes from the interaction of the ejected matter and the circumstellar material, which is the progenitor's pre-SN wind. It is thus a unique probe of both the ejected material and the SN environment. We propose a 30 ksec Chandra obs. of the type Ib/c SN 2001em (which just turned on in the radio; K. Weiler, IAUC submitted) to determine the X-ray flux to ~5% (see below for flux estimate) and temperature to ~10%. This information, combined with continued VLA obs., will determine the mass-loss rate of the progenitor, thus providing information about both the explosion environment and the nature of the progenitor. This is especially important in the case of SNe Ib/c given the association with some GRBs. Such information will provide a key piece of the puzzle in understanding the progenitor systems of SNe Ib/c (and by association, GRBs) and the aftermath of the SN (and GRB) explosion.
