Resistive Hot Accretion Flows with Anisotropic Pressure
S. M. Ghoreyshi, A. R. Khesali
Since the collisional mean free path of charged particles in hot accretion flows can be significantly larger than the typical length-scale of the accretion flows, the gas pressure…
Time Dependence of Advection Dominated Accretion Flow with a Toroidal Magnetic Field
Alireza Khesali, Kazem Faghei
The present study examines self-similarity evolution of advection dominated accretion flow (ADAF) in the presence of a toroidal magnetic field. In this research, it was assumed tha…
Thermal instability in ionized plasma
Mohsen Shadmehri, Mohsen Nejad-Asghar, Alireza Khesali
We study magnetothermal instability in the ionized plasmas including the effects of Ohmic, ambipolar and Hall diffusion. Magnetic field in the single fluid approximation does not a…
Time-Dependent of Accretion Flow with Toroidal Magnetic Field
Alireza Khesali, Kazem Faghei
In the present study time evolution of quasi-spherical polytropic accretion flow with toroidal magnetic field is investigated. The study especially focused the astrophysically impo…
Artificial viscosity in simulation of shock waves by smoothed particle hydrodynamics
M. Nejad-Asghar, A. R. Khesali, J. Soltani
The artificial viscosity is reconsidered in smoothed particle hydrodynamics to prevent inter-particle penetration, unwanted heating, and unphysical solutions. The coefficients in t…
