Rainer Diaz-Bone,Christoph Weischero characterize the kinetic energy of the grains. Further tests of the analogy with gas kinetic theory have resulted in investigations into the collective behaviour of the grains, and the diflusion coefficient. Positron Emission Particle Tracking has been used to follow the motion of a single grain w

The resulting transport of the granular material exhibits novel collective behavior, both as a function of the number of layers of parti

The main feature of this phenomenon, predicted by a hydrodynamic model and confirmed by computer simulations, are: (i) a column of a granular gas oscillates periodically with the frequency ., where . is the vibrationalfrequency, . is a positive integer number, (ii) the oscillation patterns

So far, however, neither the detailled mechanisms of formation of planetary rings nor their complex spatial and dynamic behavior, originating from inelastic particle collisions, resonances, gravitational perturbations and others, are completely understood. We give a review on the

Various factors affecting the local balance between collisional dissipation and viscous gain of energy from the systematic velocity field are considered, including gravitational encounters and collective gravitational forces besides physical impacts.

In these locations the collisionally induced outward flow of the angular momentum is perturbed by the satellite. In some cases the perturbations may be strong enough to change the direction of the angular momentum f

Free Cooling of Particles with Rotational Degrees of Freedomsurface roughness for spherical grains, but occurs for non-spherical grains, like needles, even if they are perfectly smooth. Based on the assumption of a homogeneous cooling state, we derive an approximate analytical theory. It predicts that cooling of both rough spheres and smooth needles proceeds
