SUMMARY:Exoplanet Demographics: A Journey Through Space and Time - Timothy
  Hallatt (MIT)
DTSTART:20250617T120000Z

UID:TALK227293@talks.cam.ac.uk
CONTACT:Dr Dolev Bashi
DESCRIPTION:Exoplanet demographic surveys provide a unique window into pla
 net formation and evolution. In this talk\, I will showcase three distinct
  features in the exoplanet population and offer theoretical interpretation
  of the physical mechanisms that sculpt them. I will first highlight what 
 recent measurements extending the exoplanetary census beyond the solar nei
 ghborhood can tell us about how planet formation has evolved over cosmic t
 ime. Second\, I will explore the origins of "desert dweller" planets that 
 reside deep in the "sub-Jovian desert" (2 < Rp < 10 R_Earth\, periods < 3 
 days)\, a region sparsely populated but no longer empty thanks to recent s
 urveys. I will show that "desert dwellers" may serve as laboratories to st
 udy the fate of hot Jupiters and the interiors of giant planets in exquisi
 te detail. Lastly\, I will discuss the role atmospheric photoevaporation p
 lays in carving the orbital period distribution of puffy\, gas-rich sub-Sa
 turns\; in this picture\, the sub-Saturn orbital period distribution can b
 e leveraged to estimate a fundamental property of the planet population - 
 the core mass function of gas-rich planets. I will outline the observation
 al implications of our theoretical work throughout the talk.\n
