Self-similar structure of resistive ADAFs with outflow and large-scale magnetic field
S. M. Ghoreyshi
The observations and simulations have revealed that large-scale magnetic field and outflows can exist in the inner regions of an advection-dominated accretion disc where the resist…
The self-similar structure of advection-dominated discs with outflow and radial viscosity
S. M. Ghoreyshi, M. Shadmehri
Observational evidence and theoretical arguments postulate that outflows may play a significant role in the advection-dominated accretion discs (ADAFs). While the azimuthal viscosi…
Fourier analysis of advection-dominated accretion flows
Asiyeh Habibi, Shahram Abbassi, Mohsen Shadmehri
We implement a new semi-analytical approach to investigate radially self-similar solutions for the steady-state advection-dominated accretion flows (ADAFs). We employ the usual …
Analytical solution for the structure of ADAFs
Mohsen Shadmehri
The standard Advection-Dominated Accretion Flow (ADAF) is studied using a set of self-similar analytical solutions in the spherical coordinates. Our new solutions are useful for st…
Influence of the back-reaction of streaming cosmic rays on magnetic field generation and thermal instability
Anatoly K. Nekrasov, Mohsen Shadmehri
Using a multi-fluid approach, we investigate streaming and thermal instabilities of the electron-ion plasma with homogeneous cold cosmic rays propagating perpendicular to the backg…
Vertically Self-Gravitating ADAFs in the Presence of Toroidal Magnetic Field
A. Mosallanezhad, S. Abbassi, M. Shadmehri +1
Force due to the self-gravity of the disc in the vertical direction is considered to study its possible effects on the structure of a magnetized advection-dominated accretion disc.…
