Charge Fluctuation of Dust Grains and its Impact on Dusty Wave Propagation
Barbara Atamaniuk, Krzysztof Zuchowski
Abstract
In this paper we consider the influence of dust charge fluctuations on damping of the dust-ion-acoustic waves. Fluid approximation of longitudinal electrostatic waves in unmagnetized plasmas is considered. We show that for a weak acoustic wave the attenuation depends on a phenomenological charging coefficient.
