SUMMARY:Understanding Planet Formation by Studying the Evolution of Hot Ne
 ptunes and Super-Earths - Eric Lopez (Edinburgh)

DESCRIPTION:One of the most significant advances by NASA’s Kepler Missio
 n was the discovery of an abundant new population of highly irradiated pla
 nets with sizes between that of the Earth and Neptune\, unlike anything fo
 und in our Solar System. Understanding these populations poses a fundament
 al test for models of planet formation and evolution\, with important impl
 ications for habitability and the frequency of Earth-like planets. Using m
 odels of planet evolution and atmospheric evaporation\, I will discuss two
  recent papers that shed light on the compositions and possible origins of
  these new populations. In particular\, I will show that the most highly i
 rradiated planets likely formed without large amounts of material from bey
 ond the snowlike and that the period dependence of the transition between 
 rocky and non-rocky planets can be used to constrain the origin of rocky e
 xoplanets in general.
