Abstract

The stability of weakly ionized D-type waves is discussed in the case of a layer of plasma behind the front of a Lyman continuum of hydrogen which is optically thick for quanta. It is shown that stable oscillations are possible. For the characteristic parameters of an interstellar gas, viscous effects may have a stabilizing influence only on shortwave perturbations with wavelength L≪L0 (L0 corresponds to neutral oscillations).
