Exoplanets and the road to the radius gap

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 which may effect 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, to infer the underlying population at birth.

About this Series: The MIT Planetary Lunch Seminar [PLS] is a weekly seminar series organized within the EAPS department. Colloquia topics span the range of research interests of the department’s planetary sciences research program. The seminars take place on Tuesdays from 12:15–1:30 pm, unless otherwise noted (term-time only). Speakers include members of the MIT community and visitors. Talks are intended to appeal to graduate students, postdocs, research scientists, and faculty with a background in planetary science.
