Abstract
The non-linear propagation of ion-acoustic (IA) shock waves (SHWs) in q-distributed e-p-i plasma system (consisting of inertial positive light ions as well as negative heavy ions, q-distributed electrons and positrons) has been studied. The reductive perturbation technique has been employed to drive the Burgers equation. The basic properties (polarity, amplitude, width, etc.) of the IA SHWs are found to be significantly modified by the effects of non-thermal properties of electrons and positrons, ion kinematic viscosity, temperature ratio of electrons and positrons, etc. It has been observed that SHWs with positive and negative potential are formed depending on the plasma parameters. The findings of our results obtained from this theoretical investigation may be useful in the understanding the characteristics of IA SHWs both in laboratory and space plasmas.
