Suwa, Yudai, Takiwaki, Tomoya, Kotake, Kei, Sato, Katsuhiko
We study the effects of rotation on the neutrino emission from Population III (Pop III) stars by performing a series of two-dimensional rotational collapse simulations of Pop III stellar cores. Our...
Special Relativistic Simulations of Magnetically-dominated Jets in Collapsing Massive Stars (2007)
Takiwaki, Tomoya, Kotake, Kei, Sato, Katsuhiko
We perform a series of two-dimensional magnetohydrodynamic core-collapse simulations of rapidly rotating and strongly magnetized massive stars. To study the properties of magnetic explosions for a...
Gravitational Wave Background from Population III Stars (2007)
Suwa, Yudai, Takiwaki, Tomoya, Kotake, Kei, Sato, Katsuhiko
We estimate the gravitational wave (GW) background from Population III (Pop III) stars using the results from our hydrodynamic simulations (Suwa et al. 2007). We calculate gravitational waveforms...
Magnetorotational Collapse of Population III Stars (2007)
Suwa, Yudai, Takiwaki, Tomoya, Kotake, Kei, Sato, Katsuhiko
We perform a series of two-dimensional magnetorotational core-collapse simulations of Pop III stars. Changing the initial distributions of rotation and magnetic fields prior to collapse in a...
Impact of nuclear "pasta" on neutrino transport in collapsing stellar cores (2007)
Sonoda, Hidetaka, Watanabe, Gentaro, Sato, Katsuhiko, Takiwaki, Tomoya, Yasuoka, Kenji, Ebisuzaki, Toshikazu
Nuclear ``pasta'', nonspherical nuclei in dense matter, is predicted to occur in collapsing supernova cores. We show how pasta phases affect the neutrino transport cross section via weak neutral...
Numerical study of gamma-ray burst jet formation in collapsars (2007)
Nagataki, Shigehiro, Takahashi, Rohta, Mizuta, Akira, Takiwaki, Tomoya
Toward understanding the central engine of long GRBs (2007)
Nagataki, Shigehiro, Takahashi, Rohta, Mizuta, Akira, Takiwaki, Tomoya
Magneto-driven Shock Waves in Core-Collapse Supernova (2004)
Takiwaki, Tomoya, Kotake, Kei, Nagataki, Shigehiro, Sato, Katsuhiko
We perform a series of two-dimensional magnetohydrodynamic simulations of the rotational core-collapse of a magnetized massive star. We employ a realistic equation of state and take into account the...
