The final parsec problem: aligning a binary with an external accretion disc
accretion accretion discs – black hole physics – galaxies evolution – stars formation – planets and satellites: formation
2011/10/21
We consider the interaction between a binary system (e.g. two supermassive black holes or two stars) and an external accretion disc with misaligned angular momentum. This situation occurs in galaxy me...
Short Gamma-ray Bursts: the mass of the accretion disk and the initial radius of the outflow
Short Gamma-ray Bursts:accretion disk initial radius outflow
2011/10/9
In this work we estimate the accretion-disk mass in the specific scenario of binary-neutron-star-merger with current observational data. Assuming that the outflows of short Gamma-ray Bursts (GRBs) are...
Accretion disks around kicked black holes: Post-kick Dynamics
Accretion disks kicked black holes: Post-kick Dynamics
2011/9/29
Numerical calculations of merging black hole binaries indicate that asymmetric emission of gravitational radiation can kick the merged black hole at up to thousands of km/s, and a number of systems ha...
