black holesStandard accretion disk theory is formulated which is based on the local heat balance. The energy produced by a turbulent viscous heating is supposed to be emitted to the sides of the disc. Sources of turbulence in the accretion disc are connected with nonlinear hydrodynamic instability...
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 ...
A stable Shakura-Sunyaev disk exists only for accretion rates M below a certain maximum. However, there is a critical viscosity parameter α_(crit), which is a function of radius, such that for α > α_(crit) advection-dominated solutions exist for all M. Even when α < α_(crit), ...

The meaning of ACCRETION DISK is a disk of usually gaseous matter surrounding a massive celestial object (such as a black hole) in which the matter gradually spirals in toward and accretes onto the object as a result of gravitational attraction. How to u
The collapsar model is widely accepted as one of the standard scenarios for gamma-ray bursts (GRBs). In the massive collapsar scenario, the core will collapse to a black hole (BH) surrounded by a temporary hyperaccretion disk with a very high accretion rate. The newborn BH hyperaccretion ...

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 ...
