“…The lighter electrons stick to the heavier dust grains and make them negatively charged dust particles. A great deal of literature has appeared on the topic of dusty plasmas consisting of electrons, ions and negatively charged dust grains (Rao et al 1990;Shukla et al 1991;Shukla and Mamun 2002;Mushtaq 2012, 2013;Shan and Saleem 2014).…”

“…Many theoretical investigations have been devoted to the low frequency linear and nonlinear electrostatic waves in dusty plasma consisting of electrons, ions and negatively charged dust which include dust acoustic wave (DAW) (Rao et al 1990;Shan and Mushtaq 2013), dust ion acoustic wave (Shan and Mushtaq 2012;Shan and Saleem 2014) and dust drift wave (Shukla et al 1991).…”

Nonlinear dust acoustic solitons and double layers (DLs) are investigated in a four component dusty plasma consisting of superthermal electrons, superthermal trapped ions, positive and negative dust grains. The reductive perturbation method is employed to derive Schamel Korteweg de Vries (S-KdV) equation and modified Schamel Korteweg de Vries (mSKdV) equation. It is found that the nonlinear structures only with negative potential (rarefactive) can be formed in a two-dust (both positive and negative) plasma in the presence of superthermal trapped ions. In the earlier investigations, it was reported that both rarefactive (dip) and compressive (hump) nonlinear structures are possible in the plasma having both positive and negative dust species in the absence of trapped ions. Here, it is pointed out that the ions trapping does not allow the formation of compressive nonlinear structures. The results can be used to understand the dynamics of small amplitude solitary waves and double layers in dusty plasmas of cometary tails, planetary magnetospheres and interstellar clouds.

“…[15] The current-driven electrostatic nonlinear structures like solitons and shocks have been investigated in Saturn's magnetospheric plasmas having sheared flows, stationary dust and non-Maxwellian electrons. [16] The coupling of newly studied low-frequency electrostatic current-driven mode [16] with the electromagnetic Alfvén and drift waves has been investigated in Ref. [5], where the instability conditions and the growth rates of both inertial and kinetic Alfvén waves are estimated in the night side boundary regions of Jupiter's magnetosphere.…”

An investigation is carried out for understanding the properties of ion-acoustic (IA) solitary waves in an inhomogeneous magnetized electron-ion plasma with field-aligned sheared flow under the impact of q-nonextensive trapped electrons. The Schamel equation and its stationary solution in the form of solitary waves are obtained for this inhomogeneous plasma. It is shown that the amplitude of IA solitary waves increases with higher trapping efficiency (β ), while the width remains almost the same. Further, it is found that the amplitude of the solitary waves decreases with enhanced normalized drift speed, shear flow parameter and the population of the energetic particles. The size of the nonlinear solitary structures is calculated to be a few hundred meters and it is pointed out that the present results are useful to understand the solar wind plasma.
