Abstract: | An exact solution of the problem of the acoustic wave structure in a plasma is obtained. Both plasma component are treated
as gases with specified initial temperatures and adiabatic exponents. The system of equations describing the wave profile
is solved using an original method consisting of reducing the system to the Bernoulli equation. A numerical example of the
obtained general solution of the problem of the wave profile for arbitrary parameters is given. Curves are constructed that
bound the region of existence of a stationary solitary ion acoustic wave in the parameter space.
