摘要
We show that the Hall dust magnetohydrodynamic equations admit a nonstationary dust-Alfvenic shock solution in dusty plasmas. The dust-Alfvenic shocklet (DAS) occurs on a long temporal (dust gyroperiod) and spatial (dust skin depth) scales. The present result can have relevance to acceleration of charged grains by the DAS in space dusty plasmas.
