Ion acoustic solitary waves with arbitrary amplitude have been investigated using the Sagdeev potential (SP) method in a collisionless plasma consisting of non‐isothermal electrons, positrons, and positive ions. The SP has been obtained and the dependence of large amplitude solitary structures on various plasma parameters such as ion drift velocity (v0) $({v}_{0})$, non‐thermal parameter (β) $(\beta)$, electron to positron temperature ratio (σ) $(\sigma)$, positron density (p) $(p)$, and Mach number (M) $(M)$ have been studied. It is shown that, for the same values of plasma parameters, accounting for ion drift velocity greatly corrects the solitary wave profile. [ABSTRACT FROM AUTHOR] |
