Event Details & Abstract: 

Thousands of exoplanets have been discovered, spanning orders of magnitude in planet mass and orbital separation from their host stars, with orbits both excited and dynamically cold. A large fraction are part of multi-planet systems. These observations largely represent the planet population at a single stage in their lifetimes; to account for their diversity requires an understanding of how planetary systems evolve in time. In this talk I will discuss how dynamical processes like orbital instability and interaction with a protoplanetary disk can shape planetary systems, with an emphasis on the important role played by planetary mean motion resonances.
