Kinetic models for dust coagulation in interstellar clouds. (English) Zbl 1132.82016

Summary: We propose some kinetic models which take into account different mechanisms of coagulation between two populations of dust particles inside interstellar nebulae. These models are in general nonlinear; however, at the end of the paper we perform an approximate procedure to obtain a linear transport equation even for the model which considers the most general mechanism of coagulation.
