The effects of stochastic forces on the evolution of planetary systems and Saturn's rings
Hanno Rein
The increasing number of extra-solar planets opens a new opportunity for studies of the formation of planetary systems. Resonant systems are of particular interest because their dy…
Stochastic orbital migration of small bodies in Saturn's rings
Hanno Rein, John C. B. Papaloizou
Many small moonlets, creating propeller structures, have been found in Saturn's rings by the Cassini spacecraft. We study the dynamical evolution of such 20-50m sized bodies which…
Migration of a moonlet in a ring of solid particles : Theory and application to Saturn's propellers
A. Crida, J. C. B. Papaloizou, H. Rein +2
Hundred meter sized objects have been identified by the Cassini spacecraft in Saturn's A ring through the so-called "propeller" features they create in the ring. These moonlets sho…
The Validity of the Super-Particle Approximation during Planetesimal Formation
Hanno Rein, Geoffroy Lesur, Zoe M. Leinhardt
The formation mechanism of planetesimals in protoplanetary discs is hotly debated. Currently, the favoured model involves the accumulation of meter-sized objects within a turbulent…
