SUMMARY:Exoplanets and the Road to the Radius Valley - James Rogers (Insti
 tute of Astronomy\, Cambridge)
DTSTART:20250303T140000Z
DTEND:20250303T150000Z
UID:TALK227662@talks.cam.ac.uk
CONTACT:Loren E. Held
DESCRIPTION:The observed population of small\, close-in exoplanets is bifu
 rcated into two distinct types by the so-called ‘radius valley’. In th
 is talk\, I will discuss the atmospheric escape processes that may affect 
 such planets and finally lead to the radius gap being carved out\, specifi
 cally X-ray/EUV photoevaporation\, core-powered mass loss\, and boil-off. 
 The latter process is an extreme mass loss mechanism that is triggered by 
 protoplanetary disc dispersal and may have lasting impacts on the populati
 on of small exoplanets.
