Gas-Dust Protoplanetary Disc: Modeling Primordial Dusty Clusters Evolution

Marov MY and Rusol AV

Evolution of dusty clusters in the protoplanetary gas-dust disc based on the computer modeling is addressed. The classic Newton model and method of permeable particles jointly with the developed algorithms of particles interaction are used to simulate the primordial fractal dusty clusters set up and their dependence on the parameters involved. The focus is placed on the evolution of internal structure of such clusters owing to collisions of composing original particles. The results of modeling are thoroughly discussed and are regarded as an important milestone towards the study of follow up collisional interactions of fractal dusty clusters resulting eventually to primary solid bodies formation.
