The Exocast team are joined on this episode by exoplanetary interior investigator Professor Caroline Dorn. Caroline started her career in Earth sciences and geophysics, studying for her PhD aquifer systems at the University of Lausanne, before switching her focus to the interiors of more distant worlds in 2013 with postdoctoral fellowships at the University of Bern and Zurich. As of April 2023, Caroline is an Assistant Professor for exoplanet science at ETH Zürich, and her newly established interdisciplinary exoplanet research group at the Institute for Particle Physics and Astrophysics is also part of the Center of Origin and Prevalence of Life. Caroline outlines what we can learn about the interior structure of rocky exoplanets from mass and radius measurements, as well as how these planets may form and evolve over time and whether plate tectonics is necessary for sustaining an atmosphere and for habitability. As always, Caroline also adds another interesting exoplanet to our growing list of Adopted Planets.
