The generation of spiral density waves by MRI in accretion discs
G. Mamatsashvili, D. Kobaidze, W. Mouhali +2
We investigate the linear dynamics of non-axisymmetric perturbations in Keplerian discs subject to a weak uniform vertical magnetic field in the shearing box approximation. Perturb…

Leveling of MHD turbulence imbalance in shear flows
M. Kavtaradze, G. Mamatsashvili, G. Chagelishvili +1
We investigate magnetohydrodynamic (MHD) turbulence in plane shear flows with a streamwise background magnetic field in the super-Alfvénic regime. We show that the large-scale vel…
