Title: Evolution of 3-Earth-mass protoplanets towards eventual gap
opening.

Abstract:
Several-Earth-mass protoplanets interact with the gaseous and pebble
disk in a complex way (see Chrenko et al. 2017, or Eklund & Masset
2017). The hot-trail effect arises as a consequence of accretion
heating, it raises planetary eccentricities, and may prevent resonant
captures of migrating planets. Here we study the dependence of this
effect on parameters such as the surface density, viscosity, or the
number of protoplanets. After mergers, planets are massive enough to
accrete massive gas envelopes, open gaps, and eventually Type-I
migration changes to Type-II. We are also using hydrocode results and
radiation transfer code to compute how disk would appear in ALMA
observations and whether this may constrain the properties of
embedded planets.
