SUMMARY:Planet Migration and System Coupling - Dr. Craig Agnor\, Queen Mar
 y University of London
DTSTART:20080303T160000Z

DESCRIPTION:In the solar system's present orbital configuration\, dynamica
 l coupling\nbetween the outer giant and inner terrestrial planets is relat
 ively weak.\nSeveral lines of evidence suggest that large scale planet\nmi
 gration and redistribution of mass may have occurred in the past (e.g.\,\n
 the resonant structure of the Kuiper Belt). Such global restructuring\nwou
 ld have resulted in the tuning and sweeping of the giant planets'\npertuba
 tions throughout the solar system. Further\, the outward\nmigration of Ura
 nus and Neptune may post-date the formation of the inner\nplanets (e.g.\, 
 Levison et al. 2001\, Gomes et al. 2005).\nIn this talk I will discuss i) 
 how late giant planet migration can result in\nstrong dynamical coupling b
 etween the giant and terrestrial planets\, and\nii) the implications of th
 ese interactions for the solar system's\ndynamical history.
