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, then blue showing the lowest densities. Note the dense structure on the left and right of the explosion. This simulation was performed in two dimensions, so this is a cross-section of the explosion. The simulation has to be projected into three dimensions to compare with observations. The good agreement with Chandra and Spitzer data supports the author's interpretation of the disk-like structure they observed.
