“…Recently, Abdelwahaed et al [30] employed the reductive perturbation technique to study auroral EA waves with trapped vortex hot electrons and derived a perturbed higher order modified Korteweg−de Vries equation with electron temperature and trapping effects on the electro-field and energy in auroral plasmas. Cylindrical EA solitons were later investigated in vortex plasmas [31], while the propagation of small amplitude EA solitary and shock waves [32] in unmagnetized dissipative plasma accounting for cold electron fluid, nonextensive super thermal hot electrons and static ions.…”

By performing one-dimensional particle-in-cell simulations, the nonlinear effects of electronacoustic (EA) waves are investigated in a multispecies plasma, whose constituents are hot electrons, cold electrons, and beam electrons with immobile neutralized positive ions. Numerical analyses have identified that EA waves with a sufficiently large amplitude tend to trap cold electrons. Because EA waves are dispersive, where the wave modes with different wavenumbers have different phase velocities, the trapping may lead to the mixing of cold electrons. The cold electrons finally get thermalized or heated. The investigation also shows that the excited EA waves give rise to a broad range of wave frequencies, which may be helpful for understanding the broadband-electrostatic-noise spectrum in the Earth's auroral region.

“…33,38 Many researchers used kappa distribution to investigate the effect of non-Maxwellian electrons on the propagation features of (non)linear EASs in various plasma models. 39,40 We are interested in a laboratory rich in populations of TTEs like Saturn’s magnetosphere (SMS) to study the EASs.…”

The progression of nonlinear electron-acoustic waves (EAWs) in a magnetized and collision-free plasma made up of cold inertial electrons, inertialess superthermal electrons, and stationary background ions with special reference to Saturn’s magnetosphere (SMS) is explored. The method of reductive perturbation (MRP) is employed to obtain the evolution equation (i.e., Zakharov– Kuznetsov equation (ZKE)) that governs the propagation of electron acoustic solitons (EASs). Using the elegant and efficient Hirota bilinear method (HBM), multi-soliton solutions (MSSs) of the ZKE are determined. The impact of the effects of hot-to-cold electron density ratio, magnetic field (MF) strength, and superthermality on single as well as the interaction of EASs is examined. Estimates of the values of the electric field at several radii of SMS (i.e., 12 R s − 17.8 R s, where R s is the radius of Saturn) are presented, which are found in μV/ m to mV/ m range and are in perfect agreement with the data from Cassini radio and plasma wave science wideband receiver. Moreover, the influence of the relevant plasma parameters on the interaction time and spatial extent of the interacting EASs is also explored.

“…In addition to kappa distribution, here are some other distribution functions in the fitness of the situation that match the observational data well, exceptionally the behavior of low energy electrons, and have also been used to justify different inspections for space plasmas [30][31][32][33][34][35][36]. To examine the superthermal electron's influence on the linear and nonlinear propagation characteristics of electron acoustic waves in numerous plasma models, numerous researchers have however implemented the kappa distribution [37][38][39].…”

In this research, the transmission and interaction of nonlinear electron acoustic waves (EAWs) in such an unmagnetized, homogeneous, collision-free plasma composed of hot and cold electrons together with stationary ions throughout in the background have been analyzed. For the small-amplitude limit, the Korteweg–de Vries (KdV) equation for (EAWs) have been extracted. For electron acoustic solitary waves (EASWs), using the new extended direct algebraic approach, soliton solutions have also documented. The parametric analysis demonstrated that the hot to cold electron ratio and hot electron superthermal play a key role in changing the (EASWs) amplitude. The family of semi-bright solitons, dark singular solitons, Type 1 as well as 2 single solitons, trigonometric, intermingled hyperbolic and rational solitons was constructed and tested with the assistance of the innovative package software of numerical computations. The results show that the method is clear and efficient, produces analytical results in a generalized form, and these findings can also help resolve the difficulties and predicaments in the relevant disciplines of plasma physics and may be useful for studying the relationship between two (EASWs) in astrophysical and laboratory plasma. The solutions presented in this prototype are the latest in a literature review. For physical interpretation, some randomly selected solutions are shown graphically. Conclusions are held at the end.
