Abstract

The present paper proposes using the method of physicochemical dynamics of disperse systems to study the processes occurring in protoplanetary disks—gas-dust clouds in which planets form via collisions and adhesion of dust particles. Significant attention is devoted to the dynamics of contact interactions between disperse phase particles. It is shown that consideration of the possibility of the appearance of phase contacts between particles allows the long-standing astrophysics problem of slow growth of planetesimals in protoplanetary disks to be solved.
