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…
Stable Periodic Orbits for Spacecrafts around Minor Celestial Bodies
Yu Jiang, Juergen Schmidt, Hengnian Li +2
We are interested in stable periodic orbits for spacecrafts in the gravitational field of minor celestial bodies. The stable periodic orbits around minor celestial bodies are usefu…
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…
Hamiltonian Formulation and Perturbations for Dust Motion around Cometary Nuclei
Yu Jiang, Juergen Schmidt, Hexi Baoyin +2
In this paper we analyze the dynamical behavior of large dust grains in the vicinity of a cometary nucleus. To this end we consider the gravitational field of the irregularly shape…
