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…
Formation of Pillars at the Boundaries between H II Regions and Molecular Clouds
Akira Mizuta, Jave O. Kane, Marc W. Pound +3
We investigate numerically the hydrodynamic instability of an ionization front (IF) accelerating into a molecular cloud, with imposed initial perturbations of different amplitudes.…
