“…The electron acoustic structures have many important applications in laboratory and space plasmas as solitonic and shock forms in broadband electrostatic noises (BENs). [1][2][3][4][5][6][7][8][9][10][11] Furthermore, the positron (electron) plasma emerges as a new major paradigm in the study of the solar system, pulsars, galactic nuclei, and the cosmos. [12][13][14][15][16][17][18] The positron-electron pair plasmas have published several significant publications in recent years that apply tokamak plasmas, magnetospheres, neutron stars, and active galactic nuclei.…”

The linear (nonlinear) wave properties of dissipative electron acoustic plasma have been studied. The impacts of temperatures and densities on the properties of linear real and imaginary (growth rate) plasma frequencies have been examined. The effects of viscosities in the linear growth rate are also studied. Accordingly, the significant shock-like electrostatic field in auroral plasmas has been discussed. Furthermore, the electrostatic dissipative fields have been studied to explain experimental observations. A comparison between the obtained electrostatic dissipative fields and satellite observations in auroral plasmas is briefly discussed.
