| Abstract: | In this paper, charging processes of dust grains immersed in plasma are analysed.A set of self-consistent three-fluids equations are given for dust plasma. From theseequations, fluctuation of charge on dust gtaln is studied and dispersion relations arederived for electrostatic waves in a unmagnihzed dust plasma. The influence of chargefluctuation on electrostatic waves is discussed for space dust plasma |
