Angular Energy Distribution of Collapsar-Jets
Akira Mizuta, Miguel A. Aloy
Collapsars are fast-spinning, massive stars, whose core collapse liberates an energy, that can be channeled in the form of ultrarelativistic jets. These jets transport the energy f…
Numerical Study on GRB-Jet Formation in Collapsars
Shigehiro Nagataki, Rohta Takahashi, Akira Mizuta +1
Two-dimensional magnetohydrodynamic simulations are performed using the ZEUS-2D code to investigate the dynamics of a collapsar that generates a GRB jet, taking account of realisti…
Collimated Jet or Expanding Outflow: Possible Origins of GRBs and X-Ray Flashes
Akira Mizuta, Tatsuya Yamasaki, Shigehiro Nagataki +1
We investigate the dynamics of an injected outflow propagating in a progenitor in the context of the collapsar model for gamma-ray bursts (GRBs) through two dimensional axisymmetri…
