Abstract
A general dispersion relation for low-frequency electrostatic waves in a self-gravitating pair ion-dust plasma is derived. The dispersion relation admits two classes of the Jeans instability. The growth rates and thresholds of the latter are obtained. The implication of the present work to the formation of large-scale structures in the dusty universe is highlighted.
