The Impact of a Supernova Explosion in a Very Massive Binary
Jun'ichi Sato, Masayuki Umemura, Keisuke Sawada
We consider the effect of a supernova (SN) explosion in a very massive binary that is expected to form in a portion of Population III stars with the mass higher than 100.…
Imprint of Gravitational Lensing by Population III Stars in Gamma Ray Burst Light Curves
Y. Hirose, M. Umemura, A. Yonehara +1
We propose a novel method to extract the imprint of gravitational lensing by Pop III stars in the light curves of Gamma Ray Bursts (GRBs). Significant portions of GRBs can originat…
Gas stripping by radiation drag from an interstellar cloud
Jun'ichi Sato, Masayuki Umemura, Keisuke Sawada +1
We perform two-dimensional hydrodynamic simulation on the gas stripping by radiation drag from an interstellar cloud moving in uniform radiation fields. To properly include relativ…
Two-dimensional hydrodynamic simulation of an accretion flow with radiative cooling in a close binary system
Jun'ichi Sato, Keisuke Sawada, Naofumi Ohnishi
Two-dimensional numerical simulations of an accretion flow in a close binary system are performed by solving the Euler equations with radiative transfer. In the present study, the…
