Abstract (from CDS):

Supernova 1978K is one of the oldest-known examples of the class of Type IIn supernovae that show evidence for strong interaction between the blast wave and a dense, pre-existing circumstellar medium. Here we report detections of SN 1978K at both 34GHz and 94GHz, making it only the third extragalactic supernova (after SN 1987A and SN 1996cr) to be detected at late-times at these frequencies. We find SN 1978K to be >400 times more luminous than SN 1987A at millimetre wavelengths in spite of the roughly nine year difference in ages, highlighting the risk in adopting SN 1987A as a template for the evolution of core-collapse supernovae in general. Additionally, from new VLBI observations at 8.4GHz, we measure a deconvolved diameter for SN 1978K of ∼5 milli-arcsec, and a corresponding average expansion velocity of <1500km/s. These observations provide independent evidence of an extremely dense circumstellar medium surrounding the progenitor star.
