The stability of non-uniform self gravitating system in the presence of non-uniform CRs pressure
In this paper, we try to study the equilibrium structure and stability of a non-uniform self gravitating gaseous slab in vertical direction and in the presence of Cosmic Rays (CRs). Two models have been presen...

Can the magneto rotational instability be performed in the presence of strong magnetic field?
According to previous studies, it is known that Magneto-Rotational-Instability (MRI) can produce turbulent in accretion disks and it can be the origin of viscosity in these systems. These studies showed that M...

The thermo magnetic instability in hot viscose plasmas
Magnetic Rotational Instability (MRI) can not performed well in accretion disks with strong magnetic field. Studies have indicated a new type of instability called thermomagnetic instability (TMI) in systems w...

The effect of different models of viscosity on the Rossby wave and Toomre instability in accretion disks with self gravity
Rossby Wave Instability (RWI) has a noteworthy effect on the evolution of proto planetary accretion disks. This instability depends on the density and extremum of vorticity in differentially rotating disks. Th...

The role of toroidal magnetic field in the stability of accretion disks with alpha viscosity and other viscosities
The standard thin accretion disk model predicts that the inner regions of alpha model disks, where radiation pressure is dominant, are thermally and viscously unstable. However, observations show that the brig...

The local stability of accretion disk models with considering the role of various viscosity and cooling mechanisms
The standard thin accretion disk model can explain the soft X-ray spectra of Galactic black hole systems and AGN successfully. However, there are still a few observational documents for Radiation pressure theo...

2-Recognizability by prime graph of PSL(2, p 2)
Let G be a finite group and let Γ(G) be the prime graph of G. Assume p prime. We determine the finite groups G such that Γ(G) = Γ(PSL(2, p 2)) and prove that if p ≠ 2, 3, 7 is a prime then...
