Dressed ion acoustic solitons with electron beam in Earth’s magnetosphere

ORAL

Abstract

The nonlinear aspects of Ion acoustic soliton (IASs) dynamics in electron-ion plasma in the presence of an electron beam have been extensively studied as a result of the vital importance in astrophysical sciences mainly Earth’s magnetospheric region. The study of the nonlinear wave propagation in electron-ion (e-i) plasmas is useful in understanding the dynamical behavior of plasma in astrophysical environments. In the Earth’s magnetosphere plasma system, there is always a possibility of its interaction with highly intense charged particle beam coming from outer space. Moreover, the behavior of ion acoustic solitary waves propagating in e-i plasma model is strongly dependent on the ion to electron temperature ratio, beam density ratio, and electron beam parameters. Moreover, it is found that the inclusion of the higher-order corrections results in creating new type of solitons, called humped IASs. The ion number density play important role in the basic features of the produced IASs and the associated electric fields. Based on all such observations, our brief communication has heralded a model of e-i plasma to know the various effects of an electron beam on plasma dynamics.
