In this paper propagation of the nonlinear cnoidal ion-acoustic waves in unmagnetized electron-positron-ion plasma have been studied. The nonextensivity distribution function was used to describe the plasma electrons and positrons, while plasma ions are taken high relativistic.We have used the reductive perturbation method (RPM) to study the characteristic of ionacoustic cnoidal waves in this three-component […]
In this paper, considering the importance of ion acoustic waves in nonlinear phenomena of plasma, the combined effects of nonextensivity and nonthermality parameters on the ion acoustic cnoidal nonlinear waves studied. In this regard, the hybrid Cairns-Tsallis distribution function used to describe the electrons and positrons. Conditions of formation of nonlinear ion acoustic waves and […]
