| Popis: | Propagation of ion-acoustic waves in a multicomponent plasma consisting of warm positive ions with stream velocity and two-temperature electrons has been theoretically investigated. New analytical solutions with sufficient and necessary conditions are obtained for the existence of ion-acoustic solitary waves in the plasma. It is seen that the drifting ions and two temperature electrons have key roles on the formation of ion-acoustic solitary waves in a multicomponent plasma. The critical values of the ion temperature and phase velocity of the solitary waves have been numerically estimated, which would be applicable to various physical situations. |
