Gravitational wave emission from a stellar companion black hole in presence of an accretion disk around a Kerr black hole |
Abstract _ |
We consider a system consisting of a binary black hole system, one massive and rotating, while the other is a stellar mass which is moving through an accretion disk which surrounds the massive black hole. We find the angular momentum distrubution self-consistently inside the disk and determine the exchange of angular momentum between the companion black hole and the accretion disk. We find that the gravitational wave profile will be vastly different depending on the flow parameter of the accretion disk. We show these profiles When these disks have accretion shocks, the profile also suddenly changes. In combination with electromagnetic spectral information this gravitational wave information would allow us to extract parameters such as the spin of the central black hole, mass accretion rates, mass of the black holes etc. |
