JWST data reconstructs the inner ejecta of SNR 0540-69.3 as two similar-sized fragmented lobes, implying a ~300 km/s pulsar kick under symmetry assumption and confirming low-velocity hydrogen mixing in a Type II explosion.

Late-time IR spectroscopy of SN 2024ggi shows varied line morphologies implying chemical inhomogeneity and aspherical ionization, with modeling favoring 12-15 solar mass progenitors but only high-mass energetic 3D simulations matching the observed Ni mixing extent.
Multi-dimensional simulations of a low-mass iron-core supernova remnant find that neutron-star wind and decay heating create large-scale asymmetric ejecta whose projected morphology and velocities depend strongly on viewing angle, with 24.4% of heating from non-Ni-56 chains and overall properties su
Morphological similarity between JWST images of planetary nebula PMR 1 and X-ray images of CCSN remnant RCW 103 indicates that two pairs of jets shaped RCW 103, supporting the jittering-jets explosion mechanism.
Analysis of JWST observations identifies point-symmetric morphology in SNR 0540-69.3 ejecta, interpreted as evidence for shaping by at least three jet pairs in the jittering-jets explosion mechanism.

Simulation to a Newborn Supernova Remnant from a Low-mass Iron Core Star
Multi-dimensional simulations of a low-mass iron-core supernova remnant find that neutron-star wind and decay heating create large-scale asymmetric ejecta whose projected morphology and velocities depend strongly on viewing angle, with 24.4% of heating from non-Ni-56 chains and overall properties su
