Abstract

We investigate the effect of self-consistent dust charge fluctuations on collective modes in an inhomogeneous magnetized dusty plasma. A fluid model is developed where the dust dynamics and the charge fluctuations are taken into account. It is shown that for the Rayleigh-Taylor mode both dust dynamics and charge fluctuations lead to a rapid increase of the stable regime. It is also shown that charge fluctuations can drive the drift wave unstable under certain conditions that are relevant to some astrophysical situations.
