Effect of Rotation on the Stability of a Stalled Cylindrical Shock and its Consequences for Core-Collapse Supernovae
Tatsuya Yamasaki, Thierry Foglizzo
A perturbative analysis is used to investigate the effect of rotation on the instability of a steady accretion shock (SASI) in a simple toy-model, in view of better understanding s…
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…
Stability of the Accretion Flows with Stalled Shocks in Core-Collapse Supernovae
Tatsuya Yamasaki, Shoichi Yamada
Bearing in mind the application to the theory of core-collapse supernovae, we performed a global linear analysis on the stability of spherically symmetric accretion flows through a…
Standing Accretion Shocks in the Supernova Core: Effects of Convection and Realistic EOS
Tatsuya Yamasaki, Shoichi Yamada
We investigated the structure of the spherically symmetric accretion flows through the standing shock wave onto the proto-neutron star in the post-bounce phase of the collapse-driv…
Effects of rotation on the revival of a stalled shock in supernova explosions
T. Yamasaki, S. Yamada
In order to infer the effects of rotation on the revival of a stalled shock in supernova explosions, we investigated steady accretion flows with a standing shock. We first obtained…
