[2.01] Celestial Mechanics in New Planetary Systems

S. Tremaine (Princeton U.)

The discovery of new planetary systems has dramatically broadened our perspective on planet formation and provided new arenas for the tools of celestial mechanics. I will review recent theoretical developments in our understanding of the formation and evolution of planetary systems, in particular attempts to explain two puzzles: the eccentric orbit of the planet in 16 Cyg B, and the presence of Jupiter-mass planets in orbits smaller than 0.1 AU (51 Peg, \upsilon And, etc.). I will also discuss the constraints imposed by long-term stability requirements.
