Numerical Studies of Accretion Flows onto a Neutron Star Engulfed in a Massive Star
Daiyu Sakurai, Ryuichiro Akaho, Shoichi Yamada
Massive stars commonly form binaries that can evolve into compact systems via common envelope evolution (CEE), a critical but poorly understood phase -- especially when the compani…
Multi-dimensional Features of Neutrino Transfer in Core-Collapse Supernovae
K. Sumiyoshi, T. Takiwaki, H. Matsufuru +1
We study the multi-dimensional properties of neutrino transfer inside supernova cores by solving the Boltzmann equations for neutrino distribution functions in genuinely six dimens…
Global Simulations of Magnetorotational Instability in The Collapsed Core of A Massive Star
Hidetomo Sawai, Shoichi Yamada, Hideyuki Suzuki
We performed the first numerical simulations of magnetorotational instability from a sub-magnetar-class seed magnetic field in core collapse supernovae. As a result of axisymmetric…
Neutrino oscillation and expected event rate of supernova neutrinos in adiabatic explosion model
S. Kawagoe, T. Yoshida, T. Kajino +3
We study how the influence of the shock wave appears in neutrino oscillations and the neutrino spectrum using density profile of adiabatic explosion model of a core-collapse supern…
Emergence of hyperons in failed supernovae: trigger of the black hole formation
K. Sumiyoshi, C. Ishizuka, A. Ohnishi +2
We investigate the emergence of strange baryons in the dynamical collapse of a non-rotating massive star to a black hole by the neutrino-radiation hydrodynamical simulations in gen…
Dynamics and neutrino signal of black hole formation in non-rotating failed supernovae. II. progenitor dependence
K. Sumiyoshi, S. Yamada, H. Suzuki
We study the progenitor dependence of the black hole formation and its associated neutrino signals from the gravitational collapse of non-rotating massive stars, following the prec…
