Formation, Survival, and Detectability of Objects Beyond 100 AU in Planetary Systems
The classical core accretion and the gravitational instability models for planet formation are hard pressed to form long-period planets in situ beyond 100 AU. I show that dynamical instabilities among planetary systems that originally formed multiple giant planets much closer to the host star could produce a detectable population of planets at large (10^2-10^5 AU) separations through current direct imaging campaigns.
Planet Lunch talks are held 12:00 - 13:00 and are informal in nature. Bring your (planet) lunch and bring your questions.
