Abstract

We present accretion rates obtained from three-dimensional self-gravitating radiation hydrodynamical models of giant planet growth. We investigate the dependence of accretion rates upon grain opacity and core/protoplanet mass. The accretion rates found for low-mass cores are in line with the results of previous one-dimensional models that include radiative transfer.
