Exoplanet Group Meeting - James Rogers
Title: Exoplanets and the Road to the Radius GapSpeaker:James Rogers (UCLA)Abstract: The observed population of small, close-in exoplanets is bifurcated into two distinct types by the so-called ‘radius gap’. In this talk, I will discuss the atmospheric processes that may affect such planets and finally lead to the radius gap being carved out, specifically X-ray/EUV photoevaporation, core-powered mass loss, and boil-off. I will show how one can exploit these mass-loss processes to 'rewind the clock' on planetary evolution and infer the underlying population at birth. Finally, I will discuss a new study investigating the chemical imprints of atmospheric escape on the interiors of super-Earths.
