Abstract
We examine the impact of oblique magnetic field on the Rayleigh-Taylor instability (RTI) arising in dusty plasmas. Assuming that dust grains are heavier than ions and electrons, a three-component magnetized dusty plasma is considered. A general dispersion relation is derived to investigate the effect of oblique magnetic field on the Rayleigh-Taylor instability. Variation of growth rates of Rayleigh-Taylor instability with wavenumber are shown graphically for different values of magnetic field inclination with positive y- axis. Rayleigh-Taylor instability is discussed for astrophysical situation near Saturn’s E ring in space plasma. It is found that the growth rates of Rayleigh-Taylor instability have linearly increasing pattern in the presence of oblique magnetic field.
