Abstract: | Theoretical investigation has been made on two different ultra-low-frequency electrostatic modes, namely, dust-cyclotron mode
and dust-lower-hybrid mode, propagating perpendicular to the external magnetic field, in a self-gravitating magnetized two-fluid
dusty plasma system. It has been shown that the effect of the self-gravitational force, acting on both dust grains and ions,
significantly modifies the dispersion properties of these two electrostatic modes. The implications of these results to some
space and astrophysical dusty plasma systems, especially to planetary ring-systems and cometary tails, are briefly mentioned. |
