Effects of Rotation on Standing Accretion Shock Instability in Nonlinear Phase for Core-Collapse Supernovae
Wakana Iwakami, Kei Kotake, Naofumi Ohnishi +2
We studied the effects of rotation on standing accretion shock instability (SASI) by performing three-dimensional hydrodynamics simulations. Taking into account a realistic equatio…
Three-Dimensional Simulations of Standing Accretion Shock Instability in Core-Collapse Supernovae
Wakana Iwakami, Kei Kotake, Naofumi Ohnishi +2
We have studied non-axisymmetric standing accretion shock instability, or SASI, by 3D hydrodynamical simulations. This is an extention of our previous study on axisymmetric SASI. W…
The g-mode Excitation in the Proto Neutron Star by the Standing Accretion Shock Instability
Shijun Yoshida, Naofumi Ohnishi, Shoichi Yamada
The so-called "acoustic revival mechanism" of core-collapse supernova proposed recently by the Arizona group is an interesting new possibility. Aiming to understand the elementary…
Gravitational Radiation from Standing Accretion Shock Instability in Core-Collapse Supernovae
Kei Kotake, Naofumi Ohnishi, Shoichi Yamada
We present the results of numerical experiments, in which we study how the asphericities induced by the growth of the standing accretion shock instability (SASI) produce the gravit…
Inelastic Neutrino-Helium Scatterings and Standing Accretion Shock Instability in Core-Collapse Supernovae
Naofumi Ohnishi, Kei Kotake, Shoichi Yamada
We present the results of numerical experiments, in which we have investigated the influence of the inelastic neutrino-helium interactions on the standing accretion shock instabili…
Toward Radiation-Magnetohydrodynamic Simulations in Core-Collapse Supernovae
Kei Kotake, Naofumi Ohnishi, Shoichi Yamada +1
We report a current status of our radiation-magnetohydrodynamic code for the study of core-collapse supernovae. In this contribution, we discuss the accuracy of our newly developed…
