Dust acoustic shock waves in plasmas with strongly coupled dusts and superthermal ions

The reductive perturbation method is used for deriving the Kordeweg-de Vries-Burgers (KdVB) equation in strongly coupled dusty plasmas, containing Boltzmann distributed electron and superthermal ions. We discuss the shock wave solutions and also study the effect of superthermal ions on the waves. PACS Nos: 52.35Bj, 52.35Mw, 52.35.S Nous utilisons la methode de perturbations reductrices pour obtenir l'eequation de Kordeweg-de Vries-Burgers (KdVB) dans un plasma poussiereux fortement couple; qui contient des electrons distribuesa la Boltzmann et des ions suprathermiques. Nous analysons les solutions onde de choc et etudions aussi l'effet des ions suprathermiques sur les ondes. [Traduit par la Redaction]
1. Introduction Dusty plasmas are ordinary plasmas with embedded solid microparticles. In recent years, the study of nonlinear waves in plasmas has become one of the most important topics in [...]
