Abstract

We modeled the microphysics of grain growth and sedimentation in the outer radiative part of the envelope of a protoplanet forming in the core accretion scenario of Hubickyj et al. (2005). We find that the resultant opacity is almost always lower than that generally assumed for interstellar grains, but
is higher, in some parts of the envelope, than the low opacities assumed by Hubickyj et al.
