Parameter Dependence of Transonic Accretion onto a Black Hole in the Presence of Bremsstrahlung and Synchrotron Cooling
نویسنده
چکیده
The topologies are obtained for accretion flows around black holes as the parameters, accretion rate and specific angular momentum are varied. Paczyński-Wiita pseudoNewtonian potential is used to mimic the gravitational field of a Schwarzschild black hole. Both stellar mass(14M⊙) and supermassive(10 M⊙) black holes are considered. The effects of bremsstrahlung and synchrotron cooling processes on the flow dynamics are studied. Rankine-Hugoniot conditions are checked for possible shock formation of solution branches of the topology. Stability of the branches and the boundary conditions of the flow are likely to decide the uniqueness of the solution. Running Title: Black Hole Accretion with Bremsstrahlung and Synchrotron cooling

Accretion onto a Black Hole in the Presence of Bremsstrahlung Cooling - Parameter Space Study
The dynamics of accretion onto a schwarzschild black hole is studied using Paczynski-Wiita pseudo newtonian potential. Steady state solution of the flow equations is obtained using thin disc approximation, including the effect of bremsstrahlung cooling in the energy equation. The topology of transonic solutions are got and the conditions for shock formation (Rankine-Hugoniot conditions) are che...
متن کاملStability of Accretion Disc around a Black Hole: effects of Bremsstrahlung and Synchrotron Cooling
We perform stability analysis of an accretion disc around a stellar mass black hole. The cooling of the accretion flow due to bremsstrahlung and synchrotron radiation processes are considered. The solutions with shock are perturbed at the shock location and the radial dependence of perturbation is obtained by solving the equations numerically using fourth-order Runge-Kutta method. The perturbat...
متن کاملBlack Hole Accretion in Low States: Electron Heating
Gas in an accretion flow is heated by MHD turbulence generated through the magneto-rotational instability. The viscous stress driving the accretion is intimately connected to the microscopic processes of turbulence dissipation. We show that, in a few well-observed black hole accretion systems, there is compelling evidence of efficient electron heating by turbulence or collective plasma effects ...
متن کاملBehaviour of dissipative accretion flows around black holes
We investigate the behaviour of dissipative accreting matter close to a black hole as it provides the important observational features of galactic and extra-galactic black holes candidates. We find the complete set of global solutions in presence of viscosity and synchrotron cooling. We show that advective accretion flow can have standing shock wave and the dynamics of the shock is controlled b...
متن کاملSolutions of Two Dimensional Viscous Accretion and Winds In Kerr Black Hole Geometry
We extend our previous studies of shock waves and shock-free solutions in thin accretion and winds in pseudo-Newtonian geometry to the case when the flow is two-dimensional and around a Kerr black hole. We present equations for fully general relativistic viscous transonic flows and classify the parameter space according to whether or not shocks form in an inviscid flow. We discuss the behaviors...
