Multiple physical elements to determine the gravitational-wave signatures of core-collapse supernovae
Kei Kotake
We review recent progress in the theoretical predictions of gravitational waves (GWs) of core-collapse supernovae. Following a brief summary of the methods in the numerical modelin…
Three-dimensional Hydrodynamic Core-Collapse Supernova Simulations for an Star with Spectral Neutrino Transport
Tomoya Takiwaki, Kei Kotake, Yudai Suwa
We present numerical results on three-dimensional (3D) hydrodynamic core-collapse simulations of an star. By comparing one-(1D) and two-dimensional(2D) results wit…
Impacts of Collective Neutrino Oscillations on Supernova Explosions
Yudai Suwa, Kei Kotake, Tomoya Takiwaki +2
By performing a series of one- and two-dimensional (1-, 2D) hydrodynamic simulations with spectral neutrino transport, we study possible impacts of collective neutrino oscillations…
Explosive nucleosynthesis in the neutrino-driven aspherical supernova explosion of a non-rotating 15 star with solar metallicity
Shin-ichiro Fujimoto, Kei Kotake, Masa-aki Hashimoto +2
We investigate explosive nucleosynthesis in a non-rotating 15 star with solar metallicity that explodes by a neutrino-heating supernova (SN) mechanism aided by both standi…
Effects of Rotation on Stochasticity of Gravitational Waves in Nonlinear Phase of Core-Collapse Supernovae
Kei Kotake, Wakana Iwakami Nakano, Naofumi Ohnishi
By performing three-dimensional (3D) simulations that demonstrate the neutrino-driven core-collapse supernovae aided by the standing accretion shock instability (SASI), we study ho…
