“…When viscous force is absent in the medium (figure 10(b)), we can see that the density of dust has very little change with various M. This is due to the heavy mass of the dust than ion, and also the density of dust and ion has different polarities. But from figure 10(a), we can see that the effect of viscosity has a larger impact than the effect )corresponding to the periodic solution, there exists the family of nonlinear periodic trajectories (NPT 1,0 ) [66,67]. The corresponding analytical solution of the nonlinear homoclinic trajectory (NHT T,0 ) has already been shown in figures 6(a)-7.…”

A viscous dusty plasma containing Kappa-(κ−) distributed electrons,positive warm viscous ions and constant negatively charged dust grains with viscosity have been considered to study the modes of dust-ion-acoustic waves (DIAWs) theoretically and numerically. The derivations and basic features of shock and solitary waves with different plasma parameters like Mach number, finite temperature coefficient, unperturbed dust streaming velocity, kinematic viscosity of dust etc. of this DIAWs mode have been performed. Considering the dynamical equation from Korteweg–de Vries(KdV) equation, a phase portrait has been drawn and the position of saddle point or col. and center have also been discussed. This type of dusty plasma can be found in celestial bodies. The results of this research work can be applied to study the properties of DIAWs in various astrophysical situation where κ-distributive electrons are present and careful modification of the same model can help us to understand the nature of the DIAWs of laboratory plasma as well.
