Density Waves and the Viscous Overstability in Saturn's Rings
Marius Lehmann, Juergen Schmidt, Heikki Salo
This paper addresses resonantly forced spiral density waves in a dense planetary ring which is close to the threshold for viscous overstability. We solve numerically the hydrodynam…
Viscous Overstability in Saturn's Rings: Influence of Collective Self-gravity
Marius Lehmann, Juergen Schmidt, Heikki Salo
We investigate the influence of collective self-gravity forces on the nonlinear, large-scale evolution of the viscous overstability in Saturn's rings. We numerically solve the axis…
A Weakly Nonlinear Model for the Damping of Resonantly Forced Density Waves in Dense Planetary Rings
Marius Lehmann, Juergen Schmidt, Heikki Salo
In this paper we address the stability of resonantly forced density waves in dense planetary rings. Already by Goldreich & Tremaine (1978) it has been argued that density waves mig…
