Nonlinear dynamics and multistability of dust-acoustic waves in magnetized cometary dusty plasma

Debprasad Pradhan, Debjit Dutta

Abstract The nonlinear dynamics of dust-acoustic waves (DAWs) in a six-component magnetized cometary dusty plasma comprising cold oxygen ions, kappa-distributed hot hydrogen ions, hot solar electrons, cold cometary photoelectrons and negatively charged dust grains are theoretically investigated. Using the reductive perturbation method …
