New solitary electrostatic structures for Zakharov model in subsonic limit for solar-wind

Abstract

A theoretical study of Zakharov model in subsonic limit has been investigated for plasma waves solutions via many solitary and huge structures. The electrostatic field modulations, the first integral and the rational self-focusing nonlinearly methods have been used to obtain many types of electric field, potential and density solutions in the form of bright (Dark-type) envelopes modulated wavepacket, dissipative shocks and self-focusing freak rational nonlinearly first-fourth order solutions. The results of the present investigation may be applicable to some plasma environments, such as solar-Wind and bursty Langmuir-waves that observed in cusps region.
