Planetary Ring, Meteoroid, and Dust Populations and Effects
Session ID#: 249507
Session Description:
New theoretical and observational studies of planetary rings, meteoroids, and dust. These collections of small particles are sensitive to a wide variety of dynamical phenomena and so can provide information about the sources, sinks, and transport of material. Rings can also encode detailed information about their dynamical environments such as their host planet's gravitational field. Meteoroids and dust interact with larger bodies through surface impacts and atmospheric ablation and therefore contribute to surface weathering of airless bodies and metal deposition in planetary atmospheres. Subjects to be covered include: the structure, dynamics, and composition of rings; characterization of dust populations along with their effects on planetary bodies and spacecraft; dust chemistry; hypervelocity impacts of dust and meteoroids; the interaction of planetary rings with ionospheres, magnetospheres, and interplanetary dust; and the origin and evolution of the rings.
