We study the gravitational collapse of a rotating supermassive star by means of a (3+1) hydrodynamical simulation in a post-Newtonian approximation of general relativity. This problem is particularly challenging because of the vast dynamical range in space which must be covered in the course of collapse. We evolve a uniformly rotating supermassive star from the onset of radial instability at Rp/M = 411, where Rp is the proper polar radius of the star and M is the total mass-energy, to the point… CONTINUE READING
