Journal ArticleDOI
Numerical Analysis on Standing Accretion Shock Instability with Neutrino Heating in the Supernova Cores
TL;DR: In this article, the instability of the spherically symmetric standing accretion shock wave against non-spherical perturbations is studied and a mode analysis based on the spherical harmonics decomposition is performed.
Journal ArticleDOI
Numerical analysis of standing accretion shock instability with neutrino heating in supernova cores
TL;DR: In this article, the instability of the spherically symmetric standing accretion shock wave against nonspherical perturbations was studied in the postbounce phase of supernovae.
Journal ArticleDOI
Three-dimensional simulations of standing accretion shock instability in core-collapse supernovae
TL;DR: In this paper, the authors studied nonaxisymmetric standing accretion shock instabilities, or SASI, using three-dimensional (3D) hydrodynamical simulations and found that the growth rates of SASI are degenerate with respect to the azimuthal index m of the spherical harmonics Ylm.
Journal ArticleDOI
Effects of rotation on standing accretion shock instability in nonlinear phase for core-collapse supernovae
TL;DR: In this article, the effects of rotation on standing accretion shock instability (SASI) by performing three-dimensional hydrodynamics simulations were studied. But the authors did not consider rotation on the axisymmetric flow and hardly affect sloshing modes.
Journal ArticleDOI
Stochastic nature of gravitational waves from supernova explosions with standing accretion shock instability
TL;DR: In this paper, the authors study the properties of GWs based on 3D simulations, which demonstrate neutrino-driven explosions aided by standing accretion shock instability (SASI).
