Abstract

In this investigation, the evolution of electron acoustic solitons (EASs) and electron acoustic dressed solitons formed due to the contribution of higher-order effects in a superthermal plasma in the presence of an electron beam has been examined. The reductive perturbation method is employed to derive the nonlinear Korteweg–de Vries (KdV) and KdV-type inhomogeneous equations with contribution of higher-order effects of nonlinearity and dispersion. From the solutions of these nonlinear equations, the characteristics of EASs and dressed EASs are analysed under the influence of superthermality of electrons, parameters of an electron beam and other plasma parameters. The findings of present work may be useful to explore and understand the evolution of nonlinear structures in the space and laboratory plasmas especially in Earth's magnetospheres.
