Abstract
The nonlinear propagation of dust-acoustic (DA) waves
in an obliquely propagating magnetized dusty plasma, containing
Maxwellian distributed ions of distinct temperatures (namely lower
and higher temperature Maxwellian ions), negatively charged mobile
dust grains, and Maxwellian electrons, is rigorously investigated
and analyzed by deriving the Zakharov-Kuznetsov equation. It is
investigated that the characteristics of the DA solitary waves
(DASWs) are significantly modified by the external magnetic
field, relative ion and electron temperature-ratio, and respective
number densities of two population of ions. The implications of
the results obtained from this analysis in space and laboratory
dusty plasmas are briefly discussed.
