A coagulation–disintegration model of Oort–Hulst cluster-formation

Abstract: We propose and analyse a model for the collision of highly energetic particles in which collisions cause the complete fragmentation of the particles into dust and in which particles nucleate and grow through the accretion of dust. This is inspired by the work of Oort and van Hulst. We analyse a variety of aggregation and disintegration kernels, using asymptotic techniques to illustrate the form of solutions, and find steady states and self-similar behaviour.

“…The equation (2) includes two major events, collision followed by coagulation. There are various examples of the phenomenon explained by the Oort-Hulst-Safronov equation, namely, the collision of asteroids [11], formation of saturn's rings [12], formation of protoplanetary disc around a newly formed star [13]. There are several real-world problems caused by particle coagulation such as the health hazards of sand and dust storms [14], the analysis of nano-metal dust explosions [15] and the impact on glacier mass as a result of volcanic dust accumulation [16].…”
