Gravitational waves from a dust disk around a Schwarzschild black hole
Hajime Sotani, Motoyuki Saijo
We investigate gravitational waves from a dust disk around a Schwarzschild black hole to focus on whether we can extract any of its physical properties from a direct detection of g…
Dynamical bar instability in a relativistic rotational core collapse
Motoyuki Saijo
We investigate the rotational core collapse of a rapidly rotating relativistic star by means of a 3+1 hydrodynamical simulations in conformally flat spacetime of general relativity…
Dynamical One-Armed Spiral Instability in Differentially Rotating Stars
Motoyuki Saijo, Shin'ichirou Yoshida
We investigate the dynamical one-armed spiral instability in differentially rotating stars with both eigenmode analysis and hydrodynamic simulations in Newtonian gravity. We find t…
The Collapse of Differentially Rotating Supermassive Stars: Conformally Flat Simulations
Motoyuki Saijo
We investigate the gravitational collapse of rapidly rotating relativistic supermassive stars by means of a 3+1 hydrodynamical simulations in conformally flat spacetime of general…
Collapse of a Rotating Supermassive Star to a Supermassive Black Hole: Post-Newtonian Simulations
Motoyuki Saijo, Thomas W. Baumgarte, Stuart L. Shapiro +1
We study the gravitational collapse of a rotating supermassive star (SMS) by means of a (3+1) hydrodynamical simulation in a post-Newtonian (PN) approxi- mation of general relativi…
Dynamical Bar Instability in Relativistic Rotating Stars
Motoyuki Saijo, Masaru Shibata, Thomas W. Baumgarte +1
We study by computational means the dynamical stability against bar-mode deformation of rapidly and differentially rotating stars in a post-Newtonian approximation of general relat…
