A theoretical investigation has been made of two new ultra-low-frequency electrostatic modes, namely, dust-cyclotron mode and dust-lower-hybrid mode, propagating perpendicular to the external magnetic field, in a self-gravitating magnetized two fluid dusty plasma system. It has been shown that the effect of the self-gravitational force, acting on both dust grains and ions, significantly modifie...

Supersolitons are a recent addition to the literature on large-amplitude solitary waves in multispecies plasmas. They are distinguished from the usual solitons by their associated electric field profiles which are inherently distinct from traditional bipolar structures. In this paper, dust-ion-acoustic modes in a dusty plasma with stationary negative dust, cold fluid protons, and nonthermal ele...

A review is presented of recent experiments performed on the University of Iowa DC discharge dusty plasma device on various aspects of dust acoustic waves. A brief introduction to the physics of dusty plasmas and the dust acoustic wave is first presented. Three experiments are then described: (i) observation and interpretation of large amplitude (nonlinear) dust acoustic waves; (ii) evolution o...

The observation of dust in the rings Saturn by instruments on board Voyager 1, 2, and Cassini missions triggered our interest exploring evolution electrostatic acoustic waves (DAWs) Saturnian magnetospheric dusty plasma. salient features dust-acoustic solitary have been examined means numerical simulations that adopted a fluid algorithm. We considered highly energetic non-Maxwellian ion electro...

The standard nonlinear Schrödinger Equation (NLSE) is one of the elegant equations to find detailed information about modulational instability criteria dust-ion-acoustic (DIA) waves and associated DIA rogue (DIARWs) in a three-component dusty plasma medium with inertialess super-thermal kappa distributed electrons, inertial warm positive ions negative dust grains. It can be seen that system sup...

We derive a model suitable for computer simulations of a weak ion beam with solitons of the Korteweg-de Vries (KdV) equation. This type of interactions arise in experiments on soliton generation in double plasma devices and include soliton growth, damping, or decay. Our simplified model aims at capturing only the essential physics of these interactions. The model is formulated in the context of...
