Formation of double-layers and super-solitons in a six-component cometary dusty plasma

Abstract The formation and main features of the fully nonlinear structure in a six-component dusty plasma system have been investigated using Sagdeev potential approach. By means pseudo-potential technique, fluid equations describing were diminished into single differential equation, called energy equation modified by presenting parameters addition components. For certain values configurationally parameters, our findings show that to solitary waves, double-layers super-solitons exist propagate this system. these waves studied investigating associated phase-portrait trajectories curves as well are found be very sensitive variation parameters. obtained results mainly relevant cometary it may also provide better helpful understanding nature space, astrophysical plasmas.
