Abstract

Arbitrary amplitude slow and fast electron-acoustic solitons are investigated in a four-component unmagnetised plasma model consisting of cool, warm and hot electrons, and ions. In addition to modelling all species as adiabatic fluids, the effect of neglecting inertia and treating the warm and hot electrons, respectively, as Boltzmann distributed and non-thermal species are also examined. The admissible slow and fast electron-acoustic soliton existence regions are obtained by considering both the lower and upper Mach number limits. The possibility of obtaining supersolitons is also investigated.
