Number density fields in the 3D supernova remnant models of a static 35 M_⊙ star rotating with Ω_*/Ω_K = 0.1. The ISM magnetic field is aligned with the Oz Cartesian axis and has a strength of B_ISM = 7 μG. The figures show the supernova remnant in the z = 0 (left), y = 0 (middle), and x = 0 (right) planes of the Cartesian co-ordinate system, at 50kyr after the onset of the explosion. The results are shown for an angle of θ_mag = 0° between the pulsar’s rotation axis and the direction of the local ISM. The different contours indicate regions of the supernova remnant with a 50% contribution from pulsar wind (black) and ejecta (cyan), as well as regions with a 10% contribution from Wolf-Rayet (magenta) and red supergiant wind (red) material, respectively. The black cross marks the position of the supernova explosion.
