Jittering jets promote dust formation in core-collapse supernovae

I find that the dust morphologies in some core-collapse supernova (CCSN) remnants (CCSNRs) possess jet-shaped morphologies, and propose that the properties of the jets that explode the CCSNe and their interaction with the core and envelope (if it exists) are among the factors that determine the amount of dust formed and its morphology. I find that some of the dust-rich structures in the CCSNRs Cassiopeia A and the Crab Nebula are distributed in point-symmetric morphologies, and that the dust in SN 1987A follows the bipolar morphology of the inner ejecta. Earlier studies attributed these morphologies in CCSNRs to jet shaping within the jittering jets explosion mechanism (JJEM). These dust morphologies suggest, within the framework of the JJEM, that exploding jets enhance dust formation in CCSNRs. This study contributes to the diversity of processes in which CCSN exploding jets are involved and to establishing the JJEM as the primary explosion mechanism of CCSNe.
