The jet-shaped pipe morphology in planetary nebulae and core-collapse supernova remnants
The research compared observed jet-shaped 'pipes' in core-collapse supernova remnants (CCSNRs) and planetary nebulae (PNe) with a numerical simulation based on the jittering jets explosion mechanism (JJEM). The study found that these pipes are shaped by jets, as the simulation emerged a pipe from three pairs of jets. This supports the JJEM as a primary explosion mechanism for CCSNe.
