Using the pseudopotential approach of Sagdeev, we have found analytically exact conditions for the existence of solitary waves for a system of collisionless plasmas with a mixture of warm ion-fluid and hot isothermal electrons. The analytical soliton solution for small amplitudes has also been obtained and has been compared with the published result. It is found that the finite ion temperature considerably modifies the restriction on the Mach number obtained for cold ions.

The effect of ion temperature on ion-acoustic solitary waves in the case of a two-ion plasma has been investigated using the pseudopotential approach of Sagdeev. An analytical solution for relatively small amplitudes has also been obtained. Our result has been compared, whenever possible, with the experimental result obtained by Nakamura. It is found that a finite ion temperature considerably modifies the restrictions on the Mach number obtained for cold ions.

The propagation of weakly nonlinear ion–acoustic waves in an inhomogeneous plasma is studied taking into account the effect of finite ion temperature. It is found that, whereas both the amplitude and the velocity of propagation decrease as the ion–acoustic solitary wave propagates into regions of higher density, the effect of a finite ion temperature is to reduce the amplitude but enhance the velocity of propagation of the solitary wave.
