Simulating the Shaping of Point-symmetric Structures in the Jittering Jets Explosion Mechanism

recommendations! Published in 2025 at "Publications of the Astronomical Society of the Pacific"

DOI: 10.1088/1538-3873/add08e

Abstract: We conduct three-dimensional hydrodynamical simulations of core-collapse supernovae by launching several pairs of jets into a collapsing core model and show that the jittering jets explosion mechanism (JJEM) can form a point-symmetric morphology that accounts… read more here.

DOI: 10.1088/1674-4527/19/7/95

Abstract: I present a scenario by which an accretion flow with alternating angular momentum sense on to a newly born neutron star in core collapse supernovae (CCSNe) efficiently amplifies magnetic fields and by that launches jets.… read more here.

DOI: 10.1088/1674-4527/adb4cc

Abstract: We identify an S-shaped main-jet axis in the Vela core-collapse supernova remnant (CCSNR) that we attribute to a pair of precessing jets, one of the tens of pairs of jets that exploded the progenitor of… read more here.

DOI: 10.1093/mnras/sty1053

Abstract: We find that the remnant of supernova (SN) 1987A share some morphological features with four supernova remnants (SNRs) that have signatures of shaping by jets, and from that we strengthen the claim that jets played… read more here.

DOI: 10.1093/mnrasl/slab105

Abstract: We conduct one-dimensional stellar evolution simulations in the mass range 13–20 M⊙ to late core collapse times and find that an inner vigorous convective zone with large specific angular momentum fluctuations appears at the edge of… read more here.
