A kinetic formulation developed to analyze wave propagation in dusty plasmas, which takes into account the variation of the charge of the dust particles due to inelastic collisions with electrons and ions, is utilized to study the propagation and damping of electrostatic waves with wave number exactly parallel to the external magnetic field and Maxwellian distributions for the electrons and ion...

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...

A linear stability analysis of ion-acoustic and dust-acoustic waves is carried out using a multifluid model in the presence of ionization, ion drag, and collisions of ions and dust with the background neutral gas. It is found that an unstable dust-acoustic mode of nonzero real frequency can be generated via a resonance phenomenon. This resonance develops as the frequency of the dust-ion-acousti...

Dust acoustic (DA) solitary waves are investigated in an unmagnetized dusty plasma comprising of fluid warm dust particles and kappa distributed ions. We assume the electron number density to be sufficiently depleted in this fluid model, i.e., d e n n  . We consider the usual ad hoc damping term, involving the damping rate  due to the dust–neutral collisions; and derived the modified dispers...

The nonlinear propagation of different types DANW acoustic dust waves has been investigated in a magnetized dusty plasma consisting negatively charged particles, Maxwellian electrons, and ions. Application the standard reductive perturbation theory is used to derive corresponding three-dimensional complex Ginzburg–Landau (3D-CGLE) equation which governs dynamics dust-acoustic wave packets. stat...

An experiment has been performed to study the behavior of dust acoustic waves driven at high frequencies f 100 Hz , extending the range of previous work. In this study, two previously unreported phenomena are observed—interference effects between naturally excited dust acoustic waves and driven dust acoustic waves, and the observation of finite dust temperature effects on the dispersion relatio...
