dc.description.abstract | The influence of dust rotation on the growing of dust-ion acoustic surface waves is investigated in a sharply bounded astrophysical dusty plasma containing the non-spherical dust grains and non-thermal electrons whose velocity distribution function takes the form of the generalized (r, q) distribution function, where r and q are the two spectral indices for the generalized distribution function. We assume that the angular frequency of the rotating non-spherical dust grains is close to the wave frequency to derive the resonant growth rate of the surface wave. The result shows that the surface wave becomes more unstable as the rotation frequency is increasing. If the rotation frequency is too low, the instability disappears in the domain of high wave numbers. We also have found that growth rate decreases as the moment of inertia of the rotating dust grains increases in astrophysical non-thermal plasmas. (C) 2019 Elsevier B.V. All rights reserved. | - |
