Abstract

In this investigation, propagation properties of ion-acoustic shocks (IAShs) are studied in electron–ion plasma embedded with relativistic positron beam. Employing reductive perturbation technique, we have derived the Burgers’s equation. Further, by considering the higher order effects, inhomogeneous Burgers-type equation and its solution are derived. It is found that the inclusion of higher-order corrections, results in creating new type of shocks called humped IAShs. Behaviour of different types of IAShs is seen to be dependent on the ion temperature, beam density and kinematic viscosity of electrons.
