We solve the set of hydrodynamic equations for optically thin advection-dominated accretion flows by assuming a

radially self-similar spherical coordinate system (r, q, f). The disk is considered to be in steady state and...

We obtain two-dimensional exact analytic solutions for the structure of the hot accretionflows without wind. We assume that the only non-zero component of the stress tensor is Trϕ.Furthermore, we assume that the value of ...

DISCRETIZION METHOD OF HYDRODYNAMIC EQUATIONS FOR SIMULATION OF GaN MESFETs

A finite discretization method in two dimensions has been developed and used to model electron transport in wurtzite phase GaN MESFETs....

The Jeans analysis is studied in the first post-Newtonian limit. In other words, the relativistic effects on local gravitational instability are considered for systems whose characteristic velocities and corresponding ...

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 α-prescription for the viscosity, and all ...

We find the generalized version of the Toomre’s criterion for the stability of a rotating thin

disc in the context of Eddington-inspired Born-Infeld (EiBI) gravity that possesses one free

parameter χ . To do ...

The gravitational stability of a two-dimensional self-gravitating and differentially rotating gaseous disk in the

context of post-Newtonian (PN) theory is studied. Using the perturbative method and applying the ...

to solve the set of radiation hydrodynamic equations in steady state and axisymmetric configuration, we employ self-similar technique in the radial direction. We need the reflection symmetry about the mid-plane to find gas density at the equator. For a...
