Low-frequency dust modes in a hot magnetized dusty plasma

Linear dispersion relations of low-frequency dust modes have been derived b y employing the Vlasov kinetic theory for the motions of electrons, ions, a nd dust particles in a hot and uniformly magnetized dusty plasma. Because o f the large mass of the dust grains, the finite Larmor radius effects becom e significant for dust dynamics giving rise to the existence of new low-fre quency dust modes. The importance of these low-frequency dust modes in dust coagulation and dust crystallization as well as in dusty plasmas connected to space and astrophysical situations has been pointed out.
