“…Similarly, α affects the nonlinear term in the same way and consequently affects the perturbed potential. Also, the results obtained by Sumi et al [32] represent the same behavior of the same parameter on phase velocity and the perturbed potential in the case of studying DA shock waves in a dusty self-gravitating opposite polarity plasma in the presence of trapped ions.…”

“…Later on, Sabetkar and Dorranian [30] found that the increase in the width of the DA double layers resulted due to the considered self-gravitational field enhancement. Sumi et al [32] found also that the amplitude of DA waves was modified by the presence of opposite polarity charged dust and their self-gravitational force. Mannan et al [33] found that the positive dust number density decrease leads to enhancing the amplitude of the self-gravitational solitary wave.…”

“…The self-gravitational effects have been taken in many OPDP systems [24,[27][28][29][30][31][32][33], such as dust-acoustic (DA) solitary and shock waves investigations [24,27]. The polarization force effect on the small amplitude of gravito-electrostatic excitations was investigated [28].…”

Dust-acoustic (DA) solitary and periodic waves investigations were performed in a magnetized self-gravitating dusty plasma consisting of negatively and positively charged dust grains in the presence of inertialess ions and electrons. The Korteweg–de Vries–Burger (KdVB) equation has been derived. The numerical investigations revealed the compressive or rarefactive DA solitons depending on the plasma parameters. The nonlinear homoclinic and periodic trajectories from the KdVB equation were obtained for the phase portrait profiles when employing the phase plane theory of dynamical systems. The periodic wave solution depends also on the system parameters. The present results are considered to be beneficial in understanding the nonlinear structures in experimental devices and different astrophysical environments such as the Earth’s mesosphere, cometary tails, and Jupiter’s magnetosphere.

“…The works of Mamun and Schlickeiser [40,41] have been further extended to different realistic situations of space and laboratory OPDP systems by a number authors, viz. Sabetkara and Dorranian [42], El-Taibany et al [43], Sumi et al [44], etc. Sabetkara and Dorranian [42] considered the self-gravitating OPDP system containing OPDS, kappa distributed ion species, and Boltzmann electron species to study the DA solitary waves and double layers.…”

An opposite polarity dusty plasma system (containing a few micron size massive opposite polarity dust species and singly charged ion species following Boltzmann law) is considered. The nature of dust-acoustic (DA) wave electrostatic and self-gravitational potentials are correctly found by the numerical analysis of two coupled second-order nonlinear differential equations for electrostatic and self-gravitational potentials associated with the DA waves in such an opposite polarity dusty plasma medium. These coupled nonlinear differential equations are derived from the continuity and momentum equations for positive and negative dust species, and the Boltzmann law for ion species. The basic features of the DA wave self-gravitational potential are compared with that of the DA wave electrostatic potential. The relevance of our results to space and laboratory opposite polarity dusty plasma systems is mentioned.
