Electrostatic double layers and solitary structures in non-Maxwellian unmagnetized plasmas

Abstract

A simpler method is used to obtain differential equations producing ion acoustic solitary waves and double layers (DLs) in a an unmagnetized plasma. The electrons are assumed to follow Cairns-Tsallis and Kappa distribution functions while the ions are assumed to be cold. The results are applied to F-region ionosphere where such electrostatic structures have been observed by many satellites.
