Two dimensional numerical simulations of Supercritical Accretion Flows revisited
Xiao-Hong Yang, Feng Yuan, Ken Ohsuga +1
We study the dynamics of super-Eddington accretion flows by performing two-dimensional radiation-hydrodynamic simulations. Compared with previous works, in this paper we include th…
Numerical Treatment of Anisotropic Radiation Field Coupling with the Relativistic Resistive Magnetofluids
Hiroyuki R. Takahashi, Ken Ohsuga
We develop a numerical scheme for solving a fully special relativistic resistive radiation magnetohydrodynamics. Our code guarantees conservations of total mass, momentum and energ…
Recurrent Outbursts and Jet Ejections Expected in Swift J1644+57: Limit-Cycle Activities in a Supermassive Black Hole
Tomohisa Kawashima, Ken Ohsuga, Ryuichi Usui +3
The tidal disruption event by a supermassive black hole in Swift J1644+57 can trigger limit-cycle oscillations between a supercritically accreting X-ray bright state and a subcriti…
Clumpy Outflow from Supercritical Accretion Flows
S. Takeuchi, K. Ohsuga, S. Mineshige
Significant fraction of matter in supercritical (or super-Eddington) accretion flow is blown away by radiation force, thus forming outflows, however, the properties of such radiati…
