SUMMARY: Close-in Super-Earths: The first and the last stages of planet fo
 rmation in an MRI-accreting disc - Marija Jankovic (Imperial)

DESCRIPTION:Super-Earth and mini-Neptune sized planets are abundant on sho
 rt orbits around solar and sub-solar mass stars. Could these planets form 
 close to their present orbits\, in the inner regions of protoplanetary dis
 cs? We investigate planet formation in the inner protoplanetary disc whose
  structure is governed by viscous accretion due to the magneto-rotational 
 instability (MRI). We consider the evolution of dust in the inner disc\, i
 ncluding growth\, radial drift and fragmentation due to the MRI-induced tu
 rbulence. The inner disc becomes enhanced in dust\, and we assess viabilit
 y of planetesimal formation. We also consider the accretion of atmospheres
  onto planetary cores in the MRI-accreting gas-poor inner disc. We account
  for the subsequent photoevaporation of the atmospheres\, and compare our 
 results to the observed exoplanet mass-radius relationship.
