The Helix Nebula is a low-density, stratified object with near-solar oxygen abundance (8.7), a ~1 dex sulfur deficit, and moderate helium/nitrogen enrichment placing it near the Type I boundary, with abundance variations attributed to ionization structure rather than chemical inhomogeneity.

Depositing stellar luminosity in an inner shell and cooling low-density outer cells produces a stable pulsating 3D red supergiant model for common envelope simulations without relaxation.
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.
Morphological similarity between pipe features in PNe and CCSNRs and a jet simulation is used to argue that jets formed the pipes and to bolster the JJEM for core-collapse supernovae.
