Transient growth and coupling of vortex and wave modes in self-gravitating gaseous discs
G. R. Mamatsashvili, G. D. Chagelishvili
Flow nonnormality induced linear transient phenomena in thin self-gravitating astrophysical discs are studied in the shearing sheet approximation. The considered system includes tw…

Stability and nonlinear adjustment of vortices in Keplerian flows
G. Bodo, A. Tevzadze, G. Chagelishvili +3
We investigate the stability, nonlinear development and equilibrium structure of vortices in a background shearing Keplerian flow. We make use of high-resolution global two-dimensi…
