We present results of two-dimensional general relativistic hydrodynamical simulations of constant specific angular momentum tori orbiting a Schwarzschild black hole. Upon the introduction of axisymmetric perturbations, these objects either become unstable to the runaway instability or respond with regular oscillations. Among other things, these oscillations become responsible for the emission of intense gravitational radiation, with strain amplitudes large enough to be detected by the planned interferometric detectors.

Abstract
We present results of two-dimensional general relativistic hydrodynamical simulations of constant specific angular momentum tori orbiting a Schwarzschild black hole. Upon the introduction of axisymmetric perturbations, these objects either become unstable to the runaway instability or respond with regular oscillations. Among other things, these oscillations become responsible for the emission of intense gravitational radiation, with strain amplitudes large enough to be detected by the planned interferometric detectors.File in questo prodotto:
