Over the past two decades, astronomers have discovered more than 1000 planets around nearby stars. Most of these planets have been discovered in the past two years! In this seminar, we will explore how these planets are being discovered, the prospects for characterizing these planets, and explore the properties of these new worlds. The goal of the course is to introduce students to the new field of exoplanets and to use exoplanets as an opportunity to learn Òback of the envelopeÓ physics and astronomy.
