SUMMARY:The early formation scenario for super-Earths - Chris Ormel (Amste

DESCRIPTION:Super-Earths and mini-Neptunes -- planets made up mostly of he
 avy\nelements\, but often inferred to harbour significant amounts of\nprim
 ordial (H/He) gas -- dominate the exoplanet census. Since they\norbit thei
 r host stars at periods of around 10 days (~0.1 au)\, their\nformation mus
 t have proceeded very differently than the terrestrial\nplanets in the sol
 ar system. Indeed\, our classical ideas on how\nplanet formation proceeds 
 are ill-equipped to explain the super-Earth\npopulation. I will discuss so
 me recent developments of my group that\nattempt to resolve these inconsis
 tencies\, reconciling modern planet\nformation theory with observational c
 onstraints. The topics that I\nwill highlight include: disk-planet atmosph
 ere recycling\,\nstar-disk-planet magnetic coupling\, and long-term therma
 l modeling of\nsuper-Earths.
