Ion-acoustic solitary waves in a fully relativistic ion-electron-positron plasma. (English) Zbl 1237.85032

Astrophys. Space Sci. 332, No. 2, 279-286 (2011).
Summary: A fully and coherent relativistic fluid model derived from the covariant formulation of relativistic fluid equations is used to study ion-acoustic solitary waves in a fully relativistic ion-electron-positron plasma. This approach has the characteristic to be consistent with the relativistic principle and consequently leads to a more general set of equations valid for fully relativistic plasmas with arbitrary Lorentz relativistic factor. Our results may be relevant to cosmic relativistic double- layers and relativistic plasma structures involving energetic plasma flows that may occur in space plasmas. Furthermore, they may complement and provide new insights into recently published results [G. Lu et al., Astrophys. Space Sci. 330, No. 1, 73–78 (2010; Zbl 1203.85010)].
