Abstract
Dust particles that are ubiquitously present in space interact with the space plasma and can modify the existing modes and affect the growth rate of instability. In this work, the effects of homogeneous dust on the obliquely propagating anisotropic, low beta drift magnetosonic wave, and its related kinetic instability are analyzed using the gyrokinetic model. A comparison is made of different effects due to the dust density, the ions and electrons density inhomogeneity, and the temperature anisotropy. It is observed that both the temperature anisotropy and the presence of dust species augment each other in suppressing the growth of the drift instability. Our results may, therefore, be useful in studying the propagation characteristics of drift magnetosonic wave in space near the Sun where the environment is anisotropic, and the dust species also exist.
