Abstract

Abstract: The propagation of ion acoustic ( IA ) solitary waves (SWs) is investigated in a magnetized electron-ion ( EI ) plasma with Cairns-Tsallis distributed electrons. A Zakharov-Kuznetsov (ZK) type equation is derived for the electrostatic potential via a reductive perturbation method (RPM). It is found that increasing values of non-extensive parameter q leads to reduction (enhancement) in amplitude of compressive (rarefactive) solitary structures. The amplitude of compressive (rarefactive) solitary wave (SW) decreases (increases) with increasing values of non-thermality parameter α . Furthermore, it is found that magnetic field strength Ω only affects the width of solitary structures .
