[39.06] The X-ray Light Curve of Supernova 1978K

Eric M. Schlegel (NASA-GSFC/USRA), Ed. Colbert (Un. of Maryland), Robert Petre (NASA-GSFC)

SN1978K, in NGC 1313, is a recently-recognized supernova, largely because of an X-ray observation which revealed the source to have an extreme X-ray luminosity ($\sim$10$^{39}$ ergs/s). It is the first supernova for which an X-ray light curve has been obtained in which the supernova is more than a year old. We have accumulated all of the ROSAT HRI and PSPC data currently available and present the light curve of SN1978K based upon these observations. We also present the ROSAT PSPC spectrum. Comparison will be made to the outgoing shock and reverse shock models which predict X-ray emission.
