Abstract
The nonlinear dynamics of ion acoustic shocks (IAShs) in electron-ion plasma has been studied in the presence of relativistic positron beam as a result of the vital importance in astrophysical environments mainly ionospheric region. The Korteweg-de Vries-Burgers (KdVB) equation and its oscillatory solution is derived by employing reductive perturbation method. From the solution of KdVB equation, existence of oscillatory IAShs and their characteristics are studied under the influence of various plasma parameters such as temperature of ions as well as positron, relativistic factor, viscosity of ions and different parameters of beam. The behaviour of IAShs propagating in a relativistic plasma model is strongly dependent on the ion and positron temperatures, the mass ratio and the relativistic effects. The kinematic viscosity and the equilibrium ion number density play very important roles in the basic features of the produced IAShs.
