Dust Acoustic Dressed Solitons in Jovian Magnetosphere

Abstract

In this investigation, the evolution of dust acoustic solitons (DASs) and dust acoustic dressed solitons (DADSs) have been examined in the Jovian magnetosphere. A five components plasma in which positive dust grains interact with solar wind protons, superthermally distributed electrons, ions as well as solar wind electrons is considered to explore the formation of different kinds of nonlinear structures in the Jovian magnetosphere. The Korteweg-de Vries (KdV) and inhomogenous KdV-type equations encompassing the higher-order (HO) nonlinear and dispersion (N&D) effects are derived by employing the reductive perturbation technique (RPT). With the incorporation of HO effects, a new kind of DADSs are evolved. The influence of various plasma parameters viz., superthermality of ions as well as electrons, temperature, and concentration of different species on the salient features of DASs and DADSs has been encapsulated. The findings of this work may be useful to elucidate the formation of nonlinear dust acoustic coherent structures in the Jovian magnetosphere.
