SPH Simulations of Accretion Flows onto the Supermassive Binary Black Holes from the Circumbinary Disks
Kimitake Hayasaki, Shin Mineshige, Hiroshi Sudou
We investigate the accretion flows onto the supermassive binary black holes (SMBBHs) from the circumbinary disk with the equal mass, eccentric binary on the subparsec scale, using…
Binary Black Hole Accretion Flows in Merged Galactic Nuclei
Kimitake Hayasaki, Shin Mineshige, Hiroshi Sudou
We study the accretion flows from the circumbinary disks onto the supermassive binary black holes in a subparsec scale of the galactic center, using a smoothed particles hydrodynam…
Long-term evolution of accretion discs in Be/X-ray binaries
K. Hayasaki, Atsuo T. Okazaki
We numerically study the long-term evolution of the accretion disc around the neutron star in a coplanar Be/X-ray binary with a short period and a moderate eccentricity. From three…
