Dust Acoustic Solitary Waves in Magnetized Dusty Plasma with Trapped Ions and q-Non-extensive Electrons

Nonlinear properties of dust acoustic waves (DAWs) have been investigated in magnetized dusty plasma including the effects of q-non-extensive hot electrons and trapped ions. To describe the nonlinear propagation of the wave, we have derived a KdV-like equation by using the standard reductive perturbation technique. The basic characteristics of the possible dust acoustic solitary waves (DASWs) have been analyzed numerically for a wide range of values of the plasma parameters. It is shown that the amplitude and nature of the DASWs depend sensibly on the q-non-extensive hot electrons and the trapped ions, dust temperature, strength of magnetic field and the obliqueness of propagation. The results of this investigation are expected to be useful for understanding the nonlinear propagation of DASWs in some astrophysical and laboratory plasma environments.
