Circumstellar interaction has been observed around all types of massive star
supernovae, especially at radio and X-ray wavelengths. The interaction shells
in Type Ib/c supernovae appear to be moving rapidly, although SN 1998bw remains
the only case for which the evidence points to relativistic expansion. Type IIP
supernovae have relatively low mass loss rates, consistent with moderate mass
single stars at the ends of their lives. Type IIb and some IIL and IIn
supernovae can have strong mass loss leading up to the explosion, which occurs
in a star with little H on it. The mass loss may be driven by the luminosity of
the late burning stages.
