The Origin of Hot Jupiters

Tuesday, November 8, 2016 - 1:00pm
Dr. Kevin Schlaufman (Carnegie)

It has now been 20 years since the discovery of 51 Peg b, the first planet around another Sun-like star.  Since then, many discoveries have revolutionized our understanding of how planetary systems form and evolve.  At the same time, we are still grappling with the problem posed by that first dis
