| Zusammenfassung |
| The dynamics of small (micron and submicron sized) dust particles in planetary rings are of
particular interest because, in addition to gravity, they are also sensitive to various other
forces, and thus are able to illustrate subtle processes that cannot be probed otherwise.
Studying the processes that shape planetary rings comprised of small particles
provides important constraints on their sources / sinks, transport processes, as well
as clues on the history and evolution of these rings. Here we present preliminary
results about the dynamical simulations of Uranus’ dusty rings. Our simulations
suggest that micron-sized particles in the recently discovered μ ring need to be
positively charged to remain confined in the observed region (planet-centric distance of
86,000 to 103,000 km). The ultimate goal of this study is to provide a comprehensive
theoretical understanding of the dust environment around Uranus in preparation
for in situ dust measurements and dust hazard assessments for future missions. |
