Abstract :
Arbitrary amplitude electron-acoustic solitary waves are studied in an unmagnetized plasma consisting of non-thermally distributed electrons, fluid cold electrons, electron beam and ions using the Sagdeev psuedo-potential method. Positive potential solitary structures are obtained for the typical auroral region parameters. The electric field amplitude amplitude of these potential structures ranges from few mV/m to 200 mV/m.
