Convective perturbations arising from nuclear shell burning can play an important role in propelling neutrino-driven core-collapse supernova explosions. In this work, we analyze the impact of vorticity waves on the shock dynamics and the post-shock flow using the solution of the linear hydrodynamics equations. We show that the entropy perturbations generated by the interaction of the shock with vorticity waves may play a dominant role in generating buoyancy-driven turbulence in the gain region. We estimate that the resulting reduction in the critical luminosity is 17-24%, which approximately agrees with the results of three-dimensional neutrino-hydrodynamics simulations.

  1. Effects of Rotation on 3D Core-Collapse Supernova Models for Low-Mass Progenitors

    astro-ph.HE 2026-07 conditional novelty 5.0 of 10

    For a low-mass CCSN progenitor, rotation alone weakly and non-monotonically affects explosion energy and observables; only the fastest spin yields T/|W| spiral modes and spin-kick alignment, with core spin amplified by ~4000.

  2. Impact of rotation on the accretion of entropy perturbations in collapsing massive stars

    astro-ph.SR 2025-09 conditional novelty 5.0 of 10

    Rotation has little effect on entropy perturbations falling onto a supernova shock: the sound and vortex waves they create stay below about 1% of the local sound speed, and convective eddies dominate for the modes tha...
