“…A plasma system's nonlinearity is significantly altered by such trapped particles, which has a profound impact on how solitary and shock wave phenomena evolve. The trapping of electron particles was confirmed experimentally in many works [17][18][19][20][21], and trapped electrons were used as plasma elements in several plasma frameworks to characterize the nature of the DIA shock and solitary waves [22,23]. On the other hand, researchers are recently giving their attention to making the results effectively, and they are intended to include various effects such as the magnetic effect, adiabatic effect, etc to the plasma model because these effects keep a vital role in the nonlinear wave nature [24][25][26].…”

In the case of obliquely propagated small-amplitude shock waves, in this study, we investigate the impacts of higher order nonlinearity, dust concentrations, viscosity, trapping parameter, etc., on the shock wave structures. The considered magnetized plasma system consists of three components, such as inertial positive ions (mobile), trapped electrons, and immobile negatively charged dust particles. The modified Burger equation (MBE) as well as a linear inhomogeneous equation with dominating dissipative term (in which viscous effect is significant), are derived to observe the variations in shock wave profiles. From the theoretical investigation, we observe that the higher-order nonlinearity has pronouncing effect on the shock amplitude. Furthermore, the viscosity (dust concentration) increases the shock width (the phase speed). Several mathematical techniques, such as the reductive perturbation method, the Abel’s theorem, the method of variation of parameters have been used as the supportive tools.

The propagation of dust acoustic solitary waves (DASWs) has been investigated in a magnetized dusty plasma consisting of negatively charged dust particles, nonthermal ions and nonthermal electrons. Using reductive perturbation method, the korteweg-de-vries (K-dV) equation is derived. It is found that the basic structures (such as polarity, amplitude, width) of DASWs are influenced by nonthermal ions and nonthermal electrons. The results show that both compressive and rarefactive DASWs exist in such dusty plasma. It is observed that by increasing the nonthermality parameter of ions and electrons, the nonlinear wave phase velocity increases. Furthermore, nonthermal distributed ions have more effect on the nonlinear wave phase velocity of the DASWs than nonthermal distributed electrons. The dependence of the angle that the external magnetic field makes with the propagation direction of wave on the amplitude and width of DASWs has been also investigated. It was concluded that this angle strongly affects the DASWs. Finally, the effect of the magnetic field appears only in the width and not in the amplitude of the DASWs. The findings of this study can be helpful in understanding the structures of DASWs in the dusty plasma in which both nonthermal ions and nonthermal electrons exist. Such structures can be found in different regions of space and astrophysics mediums such as the upper ionosphere and Saturn’s E-ring.

“…Alinejad [40] investigated large amplitude dust-acoustic waves (DAW) and considered the effects of trapped ions and dust temperature. Moreover, Abdikian et al [41] studied the role of each of the trapped electrons and charge dust fluctuations on dust-ion acoustic solitary waves (DIAW). Ahmad et al [42] searched for the effects of trapped electrons and tapped ions and showed that the trapping of electrons or ions significantly modifies the basic features of the dust-acoustic solitary structures that have existed in an OPDP.…”

The study of resonant wave-particle interactions (WPIs) is crucial in plasma systems wherecharged plasma particles interact via long-range electromagnetic. Our research focuses on exploringthe impact of trapping and reflection, along with the superthermality of Kappa resonance electronsand ions, on the characteristics of dust acoustic waves (DAWs) in opposite polarity dust plasma(OPDP). Both linear and non-linear analyses were conducted. Two distinct types of dust acousticmodes, namely fast and slow, have been observed in the linear regime of two different instances ofWPIs. Moving on to the non-linear regime, the Schamel KdV (SKdV) equation has been derivedusing the reductive perturbation technique. In both cases, a stationary solution in the form of adust acoustic double-layer wave (DADLW) has been successfully obtained. Our findings are highlyrelevant to astrophysical plasma environments with non-thermally trapped and reflected particles.
