If a large amplitude density pulse is launched into a plasma having equal electron and ion temperatures, Te 5Ti , Landau damping prevents the formation of a sharp leading edge ~‘‘shock’’! and the pulse spreads out. If the Landau damping is eliminated, the pulse steepens as it propagates and a shock structure is formed. This has been observed experimentally, for example, by increasing the Te /Ti...

A multi-species magnetized collisional nonthermal plasma system containing inertial ion species, non-inertial electron species following $\kappa-$ distribution, and immobile dust particles, is considered to examine the characteristics of dissipative dust-ion-acoustic (DIA) soliton modes, \textbf{theoretically parametrically}. The electrostatic solitary modes are found be associated with low fre...

The propagation of dissipative electrostatic (ion-acoustic) solitary waves in a magnetized plasma with trapped electrons is considered via the Schamel formalism. direction assumed to be arbitrary, i.e., oblique respect magnetic field, for generality. A non-Maxwellian (nonthermal) two-component considered, consisting an inertial ion fluid, cold simplicity, and electrons. (kappa) κ-type distribut...

The aim of the proposed work is to analyze soliton structures dust-ion acoustic waves obtained in framework Korteg-de Vries (KdV) equation with presence a damping term. concept electron solitary wave an unmagnetized plasma consisting superthermal electrons has been taken into consideration. KdV term derived help reductive perturbation technique and solved by using well-known homotopy analysis m...

Ion acoustic waves can be excited by electrons drifting relative to the ions in a plasma. This relative drift can be produced, in a collisional plasma, by a static electric field. In the analysis of this instability, which occurs for frequencies well below the ion plasma frequency, the electron inertia term in the momentum equation is typically neglected. A similar assumption has been employed ...

We consider the influence of dust charge fluctuations on damping of the dust-ion-acoustic waves. It is assumed that all grains have equal masses but charges are not constant in time they may fluctuate in time. The dust charges are not really independent of the variations in the plasma potentials. All modes will influence the charging mechanism, and feedback will lead to several new interesting ...
