Low-Frequency Drift Wave Instabilities in a Magnetized Dusty Plasma

An investigation is presented on the very low-frequency electrostatic drift waves due to the motion of the plasma particles in the combined effect of the static magnetic field and the inhomogeneous particle distribution in a dusty plasma using the Vlasov-kinetic model of plasmas. These modes arise and are driven unstable due to the equilibrium diamagnetic currents of heavier species of the dusty plasma. The implications of these modes to the structure formations in astrophysical situations have also been pointed out. [PACS Numbers: 52.25.Vy, 52.35.Fp, 52.35.- g, 52.35.Lv]
