Abstract

Stationary nonlinear localized electrostatic (ES) waves may be excited when an electron beam is injected into a plasma. In the present investigation, the propagation properties of two dimensional ion-acoustic solitons have been studied in a plasma composed of ion fluid, hot electrons obeying Cairns distribution and embedded with electron beam. Electron beams exist in different space and astrophysical environments and influence the properties of nonlinear structures. In this paper, we consider model equations and derive the KP equation using reductive perturbation technique. Using its solution, numerical analysis is carried out. It is seen that negative potential ion-acoustic solitons are observed under the influence of variation of beam density, beam velocity and non-thermal parameter. The findings of this investigation may be of great importance to understand the nonlinear phenomena in the upper layer of the magnetosphere where Cairns distributed hot electrons, ions and electron beam may exist.
