Puffy Planets, Hot Hosts, Probably Perturbed
Kim K. McLeod, Wellesley CollegeWith over 3500 planets now detected around other stars, you might think that we’ve seen it all. However, each new exoplanet survey turns up exotic worlds that challenge our notions of how solar systems form and evolve. One such survey is the Kilodegree Extremely Little Telescope (KELT) survey, which has a knack for finding giant planets very close to their hot host stars. I will describe recent KELT discoveries, including one giant planet that is hotter than most stars, and will explain how new kinds of analyses are uncovering a population of giant planets on highly-tilted orbits that suggest we have much yet to learn about the dynamical evolution of planetary systems. I’ll also offer a glimpse into the workings of a modestly-sized telescope at a small college and will describe how my own crew of Wellesley undergraduates contributes to KELT discoveries.
