10. SNe and SNRs with circumstellar interactions
Since 2003, about 6000 days after the explosion, the radiative energy output from SN1987A has shifted from being dominated by the release of radioactive energy from the ejecta, to the release of mechanical energy caused by the interaction of the SN blast wave with the circumstellar ring.
