Title: Properties of linear and nonlinear ion thermal waves in a pair ion plasma containing charged dust impurities

Abstract

Properties of linear and nonlinear ion thermal waves (ITWs) in pair ion plasmas containing a fraction of stationary charged (positive or negative) dust grains are investigated. For this purpose, a linear dispersion relation, a Korteweg-de Vries equation and (an energy integral of a classical potential) for linear (nonlinear) ITWs are derived from the ion continuity and momentum equations together with the Poisson equation. It is found that both the ITW frequency and the profile of the ion thermal solitary waves are significantly affected by the presence of positively/negatively charged dust grains. The present results should be useful in understanding the salient features of finite amplitude localized ion thermal solitary pulses in a pair ion plasma containing charged dust impurities.
