Cometary Dynamics: Connecting the inner and outer solar system

Duncan, M (Queen's)
Wednesday 11 November 2009, 16:00-16:50



Observations of cometary orbits in the inner solar system contain important clues to both the outer solar systemís current structure and its past dynamical evolution. I will briefly summarize numerical simulations which have studied the dynamical origins of observed comets and link the observed populations to the reservoirs from which they are currently leaking. I will then review simulations which are designed to study the dynamical origin of the reservoirs themselves. The talk concludes with a discussion of the currently unresolved issues, particularly those related to the origin and structure of the Oort Cloud.
