Abstract: | Nonlinear dust-acoustic (DA) shock waves are addressed in a nonextensive dusty plasma exhibiting self-consistent nonadiabatic
charge variation. Our results reveal that the amplitude, strength and nature of the DA shock waves are extremely sensitive
to the degree of ion nonextensivity. Significant differences in the potential function occur for very small changes in the
value of the nonextensive parameter. Stronger is the ions correlation, more important is the charge variation induced nonlinear
wave damping. |
