The distribution of ejecta in the SNR IC 443

3D ModelNoAI

The model is the result of a hydrodynamic simulation that reproduces the evolution and distribution of stellar debris (ejecta) in the supernova remnant IC 443. The colored isosurface shows the distribution of the ejecta approximately 8400 years after the supernova explosion. This isosurface corresponds to a density value which is at 1% of the peak density; the colors give the radial velocity in units of 1000 km/s on the isosurface. The outer semi-transparent surface marks the position of the forward shock; the toroidal semi-transparent structure in purple represents a molecular cloud of the interstellar medium with which the blast wave of the remnant interacts. The line of sight lies in the negative y axis.

HD simulation performed with the PLUTO code.
