Revisiting linear dynamics of non-axisymmetric perturbations in weakly magnetized accretion discs
G. R. Mamatsashvili, G. D. Chagelishvili, G. Bodo +1
We investigate linear dynamics of non-axisymmetric perturbations in incompressible, vertically stratified Keplerian discs with a weak vertical magnetic field in the shearing box ap…
Linear coupling of modes in 2D radially stratified astrophysical discs
A. G. Tevzadze, G. D. Chagelishvili, G. Bodo +1
We investigate mode coupling in a two dimensional compressible disc with radial stratification and differential rotation. We employ the global radial scaling of linear perturbation…
Electrostatic Ion Perturbations in Unmagnetized Plasma Shear Flow
A. D. Rogava, G. D. Chagelishvili, V. I. Berezhiani
The electrostatic perturbations in an unmagnetized, non-isothermal () electron-ion plasma shear flow are considered. New physical effects, arising due to the non-norma…
