Compositions of Extrasolar Planets: What Will We Learn from Our Next Planet Hunter?
Angie Wolfgang, Penn State University
Abstract: Thousands of extrasolar planets have been discovered, yet our quest to understand what they are like and how they formed is just beginning. A crucial aspect of this effort is to assess the possible compositions of these planets - that is, are they more rocky like Earth, or do they have significant layers of gas like Neptune or Uranus? A new planet hunter called the Transiting Exoplanet Survey Satellite (TESS) is designed to address this question by discovering hundreds of sub-Neptune-sized planets that orbit stars relatively close to our Sun, and subsequently measuring precise masses for at least 50 of them. In this talk I will discuss how we determine exoplanet compositions, what we know about them so far, and how our understanding may evolve thanks to TESS.
