| Résumé: | Electron-positron plasmas are believed to exist in the early universe, in active galactic nuclei, and in pulsar magnetospheres. Most of the astrophysical plasmas usually contain ions as well in addition to electrons and positrons. In this work, the ion-acoustic solitons are investigated in three-component plasmas, whose constituents are inertial ions, vortex-like electrons and positron. The properties of stationary structures are studied by pseudo-potential approach, which is valid for large amplitude |
