“…The non-linear coefficient A is the function of various plasma parameters (viz l z , , , and q), and the dispersion coefficient B is also a function of various plasma parameters (viz l z , Ω, , , and q) as mentioned in the KdV equation (28). Also it is evident that the basic characteristic features of IA solitary waves are linked with A and B [see Equation 33].…”

“…[27] Singhadiya et al investigated the IA solitary waves in unmagnetized plasma with two-temperature supertharmal electrons and Maxwellian positrons. [28] In the present study, our goal is to study the effects of Tsallis distributed electrons and thermal positrons on the propagation characteristics of IA solitary waves in magnetized EPI plasma. To the best of our knowledge, the nonlinear behavior of IA solitary waves in magnetized EPI plasmas with Tsalli distributed electrons and Maxwellian positrons have not been reported so far.…”

The propagation of ion acoustic (IA) solitary waves is investigated in a magnetized electron-positron-ion (EPI) plasma with Tsalli distributed electrons and Maxwellian positrons. A non-linear Korteweg-de Vries (KdV)-type equation is derived for the potential by using the reductive perturbation method (RPM), and its solitary wave solution is analysed. For a given set of plasma parameters, the present model supports only compressive IA solitary structures. It is found that the variation of various relevant plasma parameters, like the nonextensive parameter q, temperature ratio σ, direction cosine l z , the positron concentration γ and the magnetic field strength Ω significantly alter the characteristic properties of IA solitary waves.
