Dear Colleagues

I’d like to bring your attention to a meteoroid-focused session at the 2019 AGU Fall Meeting (San Francisco CA, 9-13 December).  Abstracts can be submitted here: https://agu.confex.com/agu/fm19/prelim.cgi/Session/75914
The submission deadline is July 31.  Please contact me or one of the other conveners if you have any questions.

P030: Planetary rings, meteoroid and dust populations and effects

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, while meteoroids and dust interact with larger bodies through surface impacts and atmospheric ablation and therefore contribute to surface weathering or 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 asteroids 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. Recent observations of the dust environment around small bodies will be highlighted.
