ABSTRACT
48In this chapter, an investigation is presented on the properties of dust acoustic (DA) solitary wave propagation in adiabatic dusty plasma including the effect of the nonthermal positive and negative ions and trapped electrons. The reductive perturbation method has been employed to derive the lower order modified Kadomstev-Petviashivili (mK-P) and higher order mK-P for dust acoustic solitary waves in a homogeneous, unmagnetized, and collisionless plasma, whose constituents are trapped electrons, singly charged positive, and negative nonthermal ions and massive charged dust particles. The stationary analytical solution of the lower order mK-P and higher order mK-P equations are solved using well-known tanh-method. These solutions are numerically analyzed and the effect of various dusty plasma constituents DA solitary wave propagation is taken into account. It is observed that both the ions in dusty plasma play a key role in the formation of DA solitary waves and also the ion concentration and trapped electrons concentration controls the transformation of compressive potentials of the waves.
