Abstract:
Planetary debris disks can reveal many characteristics of other planetary systems and their evolution. In my talk, I will review recent studies of debris disks using Spitzer focusing on the following topics: 1.) debris disk behavior with age; 2.) signposts for massive planets beyond the ice line; 3.) systems that are the sites of recent large collisions or of episodes of a high level of dynamical activity among planetesimals; and 4.) planetary systems beyond the main sequence.
Coffee and tea will be served 20 minutes prior to the seminar.
