Lewis Ball and John Kirk have continued modelling the radio emission from this fascinating supernova.
Stars spend most of their lifetime burning hydrogen into helium.
When the hydrogen fuel in the centre of a star is exhausted, the star dies leaving behind either a white dwarf or a neutron star - known collectively as compact stars. Relatively light stars whose mass is less than about six times that of our Sun, go out with a whimper, throwing off excess mass to become white dwarfs. The material thrown off by the explosion drives a strong pressure wave, or shock, out through the material which surrounded the star before it exploded. The shock accelerates particles to relativistic energies. These relativistic particles emit radio waves through synchrotron emission as they spiral around the magnetic field lines.
