Abstract
Nonlinear analysis for the electron acoustic waves (EAWs) is examined in a multicomponent plasma composed of an electron beam, inertial cold electron, inertialess superthermal hot electrons, and positive ions. The reductive perturbation technique is used to derive the Korteweg-de Vries (KdV)-Burgers equation, and the behavior of EA monotonic shocks has been investigated. The oscillatory shocks has also been examined using the nonlinear equation's solution. The dissipation effects in the beam plasma is taken into account through the viscosity term, and its influence on the propagation properties of EA shocks is studied. The impact of different plasma parameters is analyzed on the strength of monotonic and oscillatory shocks. The results of this study are emphasized in order to comprehend the dynamics of EAWs in astrophysical/space plasmas.
