On the importance of progenitor asymmetry to shock revival in core-collapse supernovae
Hiroki Nagakura, Kazuya Takahashi, Yu Yamamoto
The progenitor stars of core-collapse supernovae (CCSNe) are asymmetrically fluctuating due to turbulent convections in the late stages of their lives. The progenitor asymmetry at…
The W4 method: a new multi-dimensional root-finding scheme for nonlinear systems of equations
Hirotada Okawa, Kotaro Fujisawa, Yu Yamamoto +4
We propose a new class of method for solving nonlinear systems of equations, which, among other things,has four nice features: (i) it is inspired by the mathematical property of da…
Effects of rotation and magnetic field on the revival of a stalled shock in supernova explosions
Kotaro Fujisawa, Hirotada Okawa, Yu Yamamoto +1
We investigate axisymmetric steady solutions of (magneto)hydrodynamics equations that describe approximately accretion flows through a standing shock wave and discuss the effects o…
