MAGNETOHYDRODYNAMICS OF DUSTY PLASMAS

A set of magnetohydrodynamic (MHD) equations for multi-component dusty plasmas has been derived, by assuming that the characteristic wave fr equency is much smaller than the ion gyrofrequency. The dusty plasma M HD equations admit a linear dispersion relation which exhibits a coupl ing between dust-Alfven, dust-magnetosonic, and dust-whistler waves. T he dust inertia is found to play a major role in the wave dynamics. (C ) 1996 American Institute of Physics.
