Zonal flows in accretion discs and their role in gravito-turbulence
(University of CambridgeDepartment of Applied Mathematics and Theoretical Physics (DAMTP)St Edmund's, 2017-10-01)This thesis focuses on the evolution of zonal flows in self-gravitating accretion discs and their resulting effect on disc stability; it also studies the process of disc gravito-turbulence, with particular emphasis given ...
