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…

Stellar black hole binaries from two common envelope evolution phases in triple stellar systems

Lotem Unger, Noam Soker

We propose a triple-star evolutionary channel involving two common envelope evolution (CEE) phases to form close binary black hole (BBH) systems with an average positive effective…

Simulating observed point-symmetric core-collapse supernova morphologies with the jittering jets explosion mechanism

Jessica Braudo, Amir Michaelis, Muhammad Akashi +1

We conduct two three-dimensional hydrodynamic simulations of the jittering-jets explosion mechanism (JJEM) of core-collapse supernova (CCSN), launching three pairs of inclined oppo…

Building three-dimensional giant stellar models for common envelope simulations

Ron Schreier, Shlomi Hillel, Noam Soker

We build a three-dimensional (3D) red supergiant (RSG) stellar model for common envelope evolution (CEE) simulations by transporting a 1D stellar model to a 3D numerical grid, mimi…

JWST observations of a planetary nebula support jet-driven explosion of core-collapse supernova remnant RCW 103

Aleksei Klimov, Noam Soker

We show that the morphology of the core-collapse supernova (CCSN) remnant RCW 103 is very similar to the morphology of the brightest regions in the recently released JWST IR images…

The precessing jet axis of the supernova remnant 3C 397

Aleksei Klimov, Dmitry Shishkin, Noam Soker

We identify an S-shaped morphological feature in the enigmatic supernova remnant (SNR) 3C 397, which we attribute to the shaping by a precessing pair of jets during the explosion.…
