JWST observations support the jittering-jets explosion mechanism (JJEM) for the core-collapse supernova remnant SNR 0540-69.3
Dmitry Shishkin, Noam Soker
We examine published JWST observations of the core-collapse supernova (CCSN) remnant SNR 0540-69.3 and identify a point-symmetric morphology in its inner ejecta. Within the framewo…
Jittering jets in stripped-envelope core-collapse supernovae
Nikki Yat Ning Wang, Dmitry Shishkin, Noam Soker
Using the one-dimensional stellar evolution code MESA, we find that all our models in the initial mass range of 12-40 Mo, regardless of whether they have hydrogen-rich, hydrogen-st…
Natal kick by early-asymmetrical pairs of jets to the neutron star of supernova remnant S147
Dmitry Shishkin, Ealeal Bear, Noam Soker
We analyze the bipolar morphology of the jet-shaped core-collapse supernova (CCSN) remnant (CCSNR) S147 and its neutron star (NS) kick velocity, and suggest that two pairs of unequ…
The main jet axis of the W49B supernova remnant
Noam Soker, Dmitry Shishkin
We identify an axis connecting two opposite `ears' in the supernova remnant W49B and morphological signatures of three arcs around this axis that we claim are sections of full circ…
The Puppis A supernova remnant: an early jet-driven neutron star kick followed by jittering jets
Ealeal Bear, Dmitry Shishkin, Noam Soker
We identify a point-symmetric morphology of three pairs of ears/clumps in the core-collapse supernova remnant (CCSNR) Puppis A, supporting the jittering jets explosion mechanism (J…
The vela supernova remnant: The unique morphological features of jittering jets
Noam Soker, Dmitry Shishkin
We identify an S-shaped main-jet axis in the Vela core-collapse supernova (CCSN) remnant (CCSNR) that we attribute to a pair of precessing jets, one of the tens of pairs of jets th…
