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…

Binary Neutron Stars in Quasi-Equilibrium Circular Orbit: A Fully Relativistic Treatment
Thomas W. Baumgarte, Stuart L. Shapiro, Gregory B. Cook +2
We present a numerical scheme that solves the initial value problem in full general relativity for a binary neutron star in quasi-equilibrium. While Newtonian gravity allows for a…
