“…The DKAW is basically a different (very slow) mode compared to the usual KAW and is a result of the dispersion caused by the dust gyroradius. We expect that our results have more relevance to the nonlinear structures involving solitary waves in space and astrophysical dusty plasmas [17,25,27,28,32], where negatively charged dust particulates and Boltzmann distributed ions are the dominant plasma species. It should be added here that we have discussed the properties of nonlinear Alfvén waves for a non-relativistic dust-ion plasma.…”

“…It has been found both theoretically and experimentally that the massive charged dust grains not only change the properties of the existing plasma, but can also introduce several new types of modes [22]- [24]. A number of authors have studied coherent structures in unmagnetized [25,26] and magnetized [27,28] dusty plasmas. It was found that very low-frequency fluctuations on very long dust timescales can be excited.…”

“…Most of the electrons, because of their lower inertia, may get attached to the dust grain surface and then we can use the dust-ion plasma model [6,7]. This model has relevance to Saturn's F-ring [8], the surroundings of Halley's comet [9], and some laboratory plasma environments [10]. The charge on the dust grains influences their motion in electromagnetic fields and also affects the coagulation rate of dust particles into large bodies [11].…”

Linear instability of dust acoustic waves (DAWs) has been theoretically studied in a collisionless gravitating dust-ion magnetized plasma including the effect of dust streaming. A linear dispersion relation has been derived by using the method of normal mode analysis. Gravitational effect is found to make the low-frequency DAW mode linearly unstable in certain parametric regions. The dependence of the growth rate of the instability on various plasma parameters such as streaming of dust particles, size of the dust grain, strength of the magnetic field, obliqueness of propagation, and number density of dust particles has been numerically analyzed and presented graphically.

“…The linear and nonlinear properties of these modes are studied by considering a uniform dusty plasma model with or without external magnetic field [30][31][32][33][34][35][36][37][38][39][40][41]. But, in practice, all dusty plasma systems contain some region of inhomogeneity capable of causing drift motions and associated drift waves [42][43][44].…”

Low-frequency electrostatic dust-modes in a non-uniform magnetized dusty plasma

et al. 2004

View full text Add to dashboard Cite

A self-consistent and general description of obliquely propagating low frequency electrostatic dust-modes in a inhomogeneous, magnetized dusty plasma system has been presented. A number of different situations, which correspond to different low-frequency electrostatic dust-modes, namely, dust-acoustic mode, dust-drift mode, dust-cyclotron mode, dust-lower-hybrid mode, and other associated modes (such as, accelerated and retarded dust-acoustic modes, accelerated and retarded dust-lower-hybrid modes, etc.), have also been investigated. It has been shown that the effects of obliqueness and inhomogeneities in plasma particle number densities introduce new electrostatic dust modes as well as significantly modify the dispersion properties of the other low-frequency electrostatic dust-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.
