Turbulent Angular Momentum Transport in Weakly-Ionized Accretion Disks
Bryan Mark Johnson
Understanding the mechanism that drives accretion has been the primary challenge in accretion disk theory. Turbulence provides a natural means of dissipation and the removal of ang…

Nonlinear Stability of Thin, Radially-Stratified Disks
Bryan M. Johnson, Charles F. Gammie
We perform local numerical experiments to investigate the nonlinear stability of thin, radially-stratified disks. We demonstrate the presence of radial convective instability when…

Linear Theory of Thin, Radially-Stratified Disks
Bryan M. Johnson, Charles F. Gammie
We consider the nonaxisymmetric linear theory of radially-stratified disks. We work in a shearing-sheet-like approximation, where the vertical structure of the disk is neglected, a…
