The effect of electrostatic strong-coupling of dust particles along with their self-gravitational force has been analyzed in a three component dusty plasma. The electrons and ions forming the charge neutral background where the electron distribution is assumed to be Maxwellian while the ion distribution is non-thermal. These days, one of the key topics in plasma physics is nonlinear waves in plasma. Thus using the reductive perturbation technique to the set of hydrodynamic equation considered for an electron-ion-dusty (e-i-d) plasma, a coupled KdV equation is derived. The impact of strong coupling and self-gravitation on the solitary wave profiles, nonlinear coefficient and dispersive coefficient are studied both analytically and by numerical simulation., Comment: 19 pages, 10 figures

In this work the longitudinal wave equation through magneto-electro-elastic circular rod is studied analytically. Painlev\'e test is performed to check integrability of the equation. Exact solitary wave solutions are found by homogeneous balance method and Tanh method and are plotted using suitable values of physical parameters. A similar solution to an earlier related work [17, 20] is obtained. However we have obtained a new solution as well. Lie symmetry analysis has been done and similarity reduction of the equation is presented. Numerical results related to phase velocity etc for different materials has been derived and compared., Comment: 15 pages,13 figures, one table
