Axisymmetric accretion disks in vicinity of a central compact body are studied. In the case of non-viscous disk it is proven that all solutions for the midplane circular velocity are unstable. Hence, the pure hydrodynamic turbulence in accretion disks is possible. It is disproved the well-known arguments that an inviscid accretion disk must be sub-Keplerian. It is also demonstrated that the regular asymptotic solutions, often used in astrophysics, can lead to erroneous conclusions. It is proven… 


On dynamics of geometrically thin accretion disks
Axisymmetric accretion disks in vicinity of a central compact body are studied. For the simple models such as vertically isothermal disks as well as adiabatic ones the exact solutions to the
On the possible turbulence mechanism in accretion disks in nonmagnetic binary stars
One of the major challenges in modern astrophysics is the unexplained turbulence of gas-dynamic (nonmagnetic) accretion disks. Since they are stable, such disks should not theoretically be turbulent,
Accretion Disks Around Black Holes with Account of Magnetic Fields
Accretion disks are observed in young stars, cataclysmic variables, binary X-ray sources et al. Accretion disk theory was first developed as a theory with the local heat balance, where the whole
Three-dimensional structure of an alpha accretion disk
An analytic solution is presented to the three-dimensional problem of steady axisymmetric fluid flow through an accretion disk. The solution has been obtained through a systematic expansion in the
On the nature of the hydrodynamic stability of accretion disks in the inviscid limit
The linear stability of accretion disks is revisited. The governing equations are expanded asymptotically and solved to first order in the expansion parameterdefined by the ratio of the disk's
Hydrodynamical activity in thin accretion disks
Global transient dynamics of three-dimensional hydrodynamical disturbances in a thin viscous accretion disk
Thin viscous Keplerian accretion disks are considered asymptotically stable, even though they can show significant dynamic activity on short time scales. In this paper the dynamics of nonaxisymmetric
On the excitation of hydrodynamical turbulence in accretion discs
Our 2D numerical simulations confirm a possibility of excitation of hydrodynamic turbulence in the accretion disk due to shear instability under finite‐amplitude perturbations and at high Reynolds
The role of viscosity and cooling mechanisms in the stability of accretion disks.
A dispersion relation for linearized perturbation of a geometrically thin accretion disk is derived for an arbitrary viscosity law and cooling mechanism. Using this equation, we formulate the
Linear and weakly nonlinear analysis of the magneto-rotational-instability in thin keplerian discs
The linear instability of thin, vertically-isothermal Keplerian discs, under the influence of axial magnetic field is investigated. Solutions of the stability problem are found explicitly by
