Density distributions of the ejecta of the model M60-V0-1Foe at different evolution times (increasing from upper left to lower right). The opaque irregular isosurfaces correspond to a value of density at 1% of the peak density with one quadrant cut in order to see the radial distribution. The semi-transparent surface marks the position of the forward shock; the initially toroidal semi-transparent structures in red and cyan colors represent the inner and outer shells in the CSM respectively. The system is oriented as G26 (see Fig. 2), corresponding to the rotation angles i_x = 30°, i_y = 30°, i_z = 25° about the x, y, and z axes, respectively. The evolution time is shown in the upper left corner of each panel. A_z indicates the distance of the forward shock from the center of the explosion along the z-axis. The complete temporal evolution is available online (Movie 1).
