Scientific paper

We consider the radiative heating of an extensive pre-existing circumstellar dust shell surrounding the recent supernova in M 100. The results are consistent with observations of Merrill (IAUC 3444) of a thermal infrared excess in this object after ˜260 days. We also examine emission by interstellar dust grains in the galactic plane of M100. Although the derived fluxes are too low by ˜103, re-emission by interstellar dust heated by supernovae in Local Group galaxies should be detectable for a long time after outburst.
