Abstract
The existence of symmetric and antisymmetric stationary localized solutions for nonlinear amplitude-modulated Langmuir waves and circularly polarized electromagnetic waves in plasmas is considered. It is shown that the antisymmetric Langmuir solitons exist in the entire range of the Mach number, namely, 0<M<1, whereas antisymmetric electromagnetic solitons exist for all values of the Mach number. The parameter regions for the existence of different types of symmetric soliton solutions are obtained explicitly. It is found that both the density-hump and the density-dip electromagnetic solitons exist for subsonic as well as supersonic values of the Mach number.
