The effect of dust size distribution and dust charge fluctuation on dust acoustic solitary waves in a magnetized dusty plasma

Dust acoustic solitary waves in a magnetized dusty plasma are studied taking into account the effect of dust size and dust charge variations. Using the analytical and numerical results the influence of different plasma parameters on dust acoustic solitary waves are examined. It is observed that the dust size distribution and dust charge variation have significant contributions on the characteristics of dust acoustic solitary waves. (C) 2012 American Institute of Physics.
