Jx. Ma et My. Yu, LANGMUIR WAVE INSTABILITY IN A DUSTY PLASMA, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 50(4), 1994, pp. 180002431-180002434
By means of a self-consistent theory for dust charging, it is shown th
at the dust-charge relaxation process leads to an instability of the L
angmuir waves.
