Abstract
The behavior of ion acoustic solitary waves (IASWs) in an electron-ion plasma with spatially varying ion temperatures is studied using the reductive perturbation method. In this case, the relative temperature (σ) is considered a first-order perturbation. The modified Korteweg–de Vries (mKdV) equation is obtained to describe the wave behavior in which σ is a critical parameter of the model. The propagated localized ion-acoustic wave is affected by the temperature perturbation area while the amplitude of the ion acoustic soliton decreases after the interaction with perturbation.
