Accumulation processes in the primitive solar nebula.

Abstract

Particle accumulation processes are discussed for a variety of physical environments, ranging from the collapse phase of an interstellar cloud to the different parts of the models of the primitive solar nebula constructed by Cameron and Pine (1973). The interstellar collapse phase, the settling of particles to the control plane, processes in the convective zone, the accumulation of planetary bodies, and gas accretion are discussed. Attention is given to the formation of satellites, angular momentum aspects of star formation, the formation of comets, the formation of Mercury, the T Tauri solar wind, the evolution of the terrestrial planets, the radial distances of the planets, and the dissipation of excess solids.
