Jet-like features in supernova remnants

3D ModelNoAI

The manifold phases in the evolution of a core-collapse (CC) supernova (SN) play an important role in determining the physical properties and morphology of the resulting supernova remnant (SNR). This model aims to bridge the gap between CC SNe and their remnants by investigating how post-explosion anisotropies in the ejecta influence the structure and chemical properties of the remnant at later times. The model describes the clipped distributions of iron (purple), silicon (green), and oxygen (blue) at the age of 5000 years after the SN event (to inspect the SNR interior). The distribution of particle number density is given in units of cm^-3 (see color bar at the upper left corner). Two jet-like features are evident in the distributions and reflect large-scale anisotropies developed soon after the CC.
