Simulation of advective accretion flows around black holes under various outer boundary conditions
Rajiv Kumar, Seong-Jae Lee
We simulated various accretion disc structures with viscous hydrodynamic (HD) flow around a black hole (BH). We found that the structure of the accretion disc is significantly infl…
A new prospect for jet origin and spectral state transitions with three hybrid accretion flows around black holes
Rajiv Kumar, Ye-Fei Yuan
There is a very popular two-zone accretion disk model that the inner part of the non-advective Keplerian disk (Shakura-Sunyaev disk) can produce hot advection-dominated accretion f…
Radiative energy from a reconnection region around massive black hole
TianLe Zhao, Rajiv Kumar
In the previous numerical study, we find the blob formation and ejection in the presence of magnetic reconnection in the environment of the hot flow of the accretion disk. Based on…
Jets and spectral states with three-components of accretion flow around a black hole
Rajiv Kumar, Ye-Fei Yuan
It is generally believed that high energy radiation (power-law components) can be mostly produced by a hot corona gas in the accreting black holes. There is a very popular hybrid d…
Review the possible advective disk structures around a black hole with two-type gas inflows
Rajiv Kumar, Ye-Fei Yuan
We studied the general advective accretion solutions around the Kerr black hole (BH) with investigating two types of inflow gases at the outer accretion boundary (AB). We classifie…
Blob formation and ejection from the radiative inefficient accretion flow around massive black hole
Tian-Le Zhao, Ye-Fei Yuan, Rajiv Kumar
We study the small scale magnetic reconnection above the radiative inefficient accretion flow around massive black hole via 2D magnetohydrodynamics (MHD) numerical simulation, in o…
