Planetary accretion from planetesimals to protoplanets is investigated using three-dimensional N-body simulations. The effect of gas drag due to solar nebula is included and realistic-sized planetesimals with a standard material density are used, with which the growth time scale of planetesimals is
We have constructed a numerical simulation of the formation of water-ice planetesimals in the outer solar nebula which incorporates global turbulence, condensation and sublimation of H 2 O, and collisional accumulation. Global turbulence based on the Kolmogorov turbulence spectrum is imposed on a tw
Current models of the formation of km-sized planetary building blocks, or planetesimals, by collisional accretion require unrealistically low collision velocities or ad hoc assumptions about sticking in order for growth to occur. Collision velocities in the protoplanetary nebula increase with increa
