Title:
The long-term evolution of orbits in planetary systems
Date: Thursday, June 19th, 2008
Time: 16:00
Venue: Villa Bazzoni

Abstract:
The behavior of planetary orbits over very long terms remains
incompletely understood despite three centuries of study starting with
Newton. Understanding this behavior is central to many issues of
planetary science: Why are the planets so regularly spaced? How has
the Earth's orbit evolved throughout geological history? What
determines the properties of extrasolar planets? N-body integrations
allow us to follow the motion of planets reliably for billions of
years, and thereby inform us about the evolution and current
properties of planetary systems, and the ultimate fate of the Earth
and other planets.
