Abstract

The influence of the ion temperature on the properties of ion-acoustic solitons is considered. The critical parameters, the role of reflected ions, and the soliton profile are analyzed. The soliton evolution is studied using numerical simulations. The stability of stationary solutions is demonstrated. The results obtained are compared with the Korteweg-de Vries soliton and available experimental data.
