Scientific paper

Based on the ideas of Eneev and Kozlov, coagulation theory is used to investigate the evolution of the dust model of the protoplanetary disk, i.e., a swarm of spheres moving in a single plane along circular orbits around the attracting center and accumulating in collisions. An analytical solution to the coagulation equation is obtained. Various features of evolution are observed, including the excitation of circular standing density waves as the instability modes of a differentially rotating disk of accumulating bodies; and a close connection between the radial mass redistribution with the accumulation of the intrinsic angular momentum of the bodies.
