Scientific paper
A three-dimensional numerical model is developed to study the dynamical evolution of large size planetary embryos under mutual gravitational perturbations in the presence of the sun, collisional accretions, and spin angular momentum exchanges at collisions. Experiments are distributed in three classes, each class being characterized by the initial torus in which the planetary embryos move. It is proposed that during the intermediate stage of accretions rotations are homogenized with growing planetesimals having preferentially an equilibrium spin period of a few hours and a near zero obliquity (direct spin).
