Princeton University Summer Astrophysics Colloquia

The success of ground-based transit and RV surveys, and the Kepler/K2 and TESS missions, have shifted the exoplanet field from pure discovery to a combination of discovery, demographic analysis, and detailed characterization, especially for exoplanet atmospheres. We are using data from the TESS, Kepler/K2, and ground-based transit surveys to find keystone planetary systems around bright stars (those well suited for atmospheric observations) that can help address specific questions about planet formation and evolution. We are also studying the birthplaces of planets by searching for occultations of newly formed stars by their protoplanetary disks. These systems provide insight into the conditions required for planet formation. I will describe our recent results from both projects and discuss how we will study these types of objects in future surveys.
