Accretion of Electrons/Ions on Dust Particles
Orbital model is the simplest model of accretion of electrons/ions on dust particles and the results have been used extensively in complex plasma kinetics. The model assumes that the number of collisions with gaseous species, suffered by ions/electrons is negligible as compared to the number of accretions on the dust particles. It is also of interest to realize that, from classical considerations, the results for a monotonically varying electric potential around a charged particle do not depend on the nature of the variation but only on the electric potential of the particle with reference to the free plasma. Quantum effects, charge exchange ion collisions with neutral atoms and ion trapping also play an important role in accretion, which has been highlighted.
