When the black hole is chosen to be rotating, the sonic locations of the accretion disk get shifted or disappear, making the disk unstable. To bring it into the stable situation, the angular momentum of the accreting matter has to be reduced/enhanced (for co/counterrotating disk) by means ...
The existence of maximum temperature of the disk for model with the viscosity parameterα= 0:5. For model withα= 0:01 is shown the absence of optically thin regions for any values of the of accretion rate.The Twelfth Marcel Grossmann Meeting:On Recent Developments in Theoretical and ...
We find that when the black hole mass and spin are allowed to increase, constant angular momentum disks undergo a runaway instability on a dynamical timescale (a few orbital periods). However, our simulations show that a slight increase of the specific angular momentum of the disk outwards ...
In this paper, we study the shadows and images of the accretion disk of Kerr–Newman (KN) black hole (BH) in modified gravity (MOG) theory by using the backward ray-tracing method. And, the influence of spin parameter (a), charge (Q), and MOG parameter (α) on the observed features...

The analysis yields a unique, self-similar solution for the structure of the coupled disk/wind system. Interesting features of the new solution include the relativistic character of the outflow in the vicinity of the radius of marginal stability, which may help to explain the formation of ...
Although no-one has ever actually seen a black hole or even its event horizon, this accretion disk can be seen, because the spinning particles are accelerated
AF did not consider the Kerr black hole. The rotation of the black hole affects the behavior of neutrinos. In addition the rotation of the black hole makes the inner radius of the accretion disk smaller. These effects may drastically change EDR differently from the case for the ...
