Simulation of Kepler Supernova Explosion

This video shows a simulation of the Kepler supernova as it interacts with material expelled by the giant star companion to the white dwarf before the latter exploded. It was assumed that the bulk of this material was expelled in a disk-like structure, with a gas density that is ten times higher at the equator, running from left to right, than at the poles. The colors represent the density of the gas, using a rainbow distribution, with red showing the highest densities, followed by orange, yellow and green,
