Non-Dissipative Saturation of the Magnetorotational Instability in Thin Disks
Edward Liverts, Yuri Shtemler, Michael Mond +2
A new non-dissipative mechanism is proposed for the saturation of the axisymmetric magnetorotational (MRI) instability in thin Keplerian disks that are subject to an axial magnetic…

Linear and nonlinear evolution of the vertical shear instability in accretion discs
Richard P. Nelson, Oliver Gressel, Orkan M. Umurhan
(Abridged) We analyse the stability and evolution of power-law accretion disc models. These have midplane densities that follow radial power-laws, and have either temperature or en…

Potential vorticity dynamics in the framework of disk shallow-water theory: II. Mixed Barotropic-Baroclinic Instability
O. M. Umurhan
We extend exploration of potential vorticity instabilities in cold astrophysical disks whose mean states are baroclinic. In particular, we seek to demonstrate the potential existen…
