Abstract

We investigate the properties of rapidly rotating black hole generated by gravitational collapse of rotating relativistic stars by means of 3 + 1 hydrodynamic simulations in general relativity. Here we focus on the multipole moment of the dynamical black hole to extract some features in dynamical spacetime. We find that the dynamic black hole approaches to a stationary Kerr black hole after the damping timescale of the dynamic black hole from black hole formation. Therefore the existence of the quasi-periodic gravitational waves after the ringdown may connect to the instability of the fluid fragments around the black hole, which forms a disk.
