“…Thus, we can clearly assume that in DIA mode there is no significant effect of dust charge fluctuation. Therefore, the dust charge can be assumed to be constant [45,46]. In this manuscript, we have all along taken 'q = 1'.…”

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.

“…Misra [7] used the perturbative method and derived the KdVB equation to explain DIA shocks through a quantum dusty plasma, taking into consideration the kinematic viscosity of species of ions. Furthermore, El-Hanbaly et al [8] examined the dust viscosity influence on DA waves through dusty plasma by deriving KdV-Burgers equations.…”

The nonlinear wave propagation in dusty plasmas has received great interest in recent decades due to its significance in interpreting some astrophysical phenomenon. Wave propagation in dust-particle plasmas is likely to differ significantly from that in normal plasmas. Depending on their time scales, several types of acoustic waves propagate in dusty plasmas. The propagation of DIA waves was investigated through a system of multi-component dusty plasma. The study shows the effect of the magnetic field and superthermal parameters on the Sagdeev potential. The Sagdeev potential falls with decreasing ω ci values and rising superthermal parameter k values. Bifurcation analysis is taken into our consideration and shown graphically under the two conditions (A > 0 ) and (A < 0). The presented theoretical work is useful in fully understanding disturbances of the electrostatic in space dusty plasmas.

“…In a recent report, El-Hanbaly et al discussed the effect of trapped ions on the formation of shock waves in dissipative dusty plasma and they discussed the effect of trapped (free) ion temperature, propagation time etc on shock wave formation as well as on the energy of the solitons and electrostatic field of the waves [15]. In another report El-Hanbaly et al [16] discussed the effect of dissipative properties of plasma on the linear and nonlinear properties of dust acoustic solitary waves in the presence of non-thermal ions for a space plasma environment. It was concluded that dissipative parameters (viscosity) and the temperature ratio of ions to electrons plays an important role in controlling the behavior of the monotonic oscillatory shock wave phenomenon as well as the solitons.…”

The formation and propagation of nonlinear dust acoustic waves (DAWs) as solitary and solitary/shock waves in an unmagnetized, homogeneous, dissipative and collisionless dusty plasma comprising negatively charged micron sized dust grains in the presence of free and trapped electrons with singly charged non-thermal positive ions is discussed in detail. The evolution characteristics of the solitary and shock waves are studied by deriving a modified Korteweg-de Vries-Burgers (mKdV-Burgers) equation using the reductive perturbation method. The mKdV-Burgers equation is solved considering the presence (absence) of dissipation. In the absence of dissipation the system admits a solitary wave solution, whereas in the presence of dissipation the system admits shock waves (both monotonic and oscillatory) as well as a combination of solitary and shock wave solutions. Standard methods of solving the evolution equation of shock (solitary) waves are used. The results are discussed numerically using standard values of plasma parameters. The findings may be useful for better understanding of formation and propagation of waves in astrophysical plasma.
