Abstract
In a magnetized inhomogeneous plasmas, usual version of the KdV equation is found to modify by presence of charged dust grains. The density gradient in the plasma shows its dependence on the recombination rate, ion to electron temperature ratio, obliqueness of the magnetic field and the drift velocity of the ions. In the said plasma, only the compressive solitary structures are found to propagate corresponding to two different types of modes. A significant effect of magnetic field and charged dust grains is found on these structures, though these structures show weak dependence on the ionization rate of neutral atoms. Interestingly the solitons with prominent tailing structures are evolved in the plasma under the effect of stronger density gradient and higher recombination.
