Characterizing Planetary Systems
--- Ours and Theirs ---
with the Spitzer Space Telescope

David E. Trilling

Abstract

For eons, people have wondered whether our Solar System is unique in the galaxy. The technological advance of the infrared Spitzer Space Telescope allows us to look anew at this question. Spitzer is particularly useful for measuring the properties of dust around other stars and the properties of asteroids in our Solar System. Each of these studies offers independent insight into the processes of planetary system formation and evolution. Even better, studying these two seemingly disparate subjects together allows us to compare our Solar System directly to other planetary systems. I will present our latest results on these topics, and discuss how these results are leading toward a more universal understanding of planetary system evolution.
