“…Under certain conditions, the combined Kappa-Cairns (CKC) distribution (Debnath and Bandyopadhyay 2020) can be formulated by considering the Cairns distribution and the Kappa distribution in the background. Many authors (Aoutou et al 2008;Abid et al 2015;Debnath and Bandyopadhyay 2020;Saini et al 2022;Shahzad et al 2022;Kaur et al 2023;Mehdipoor 2022;Mehdipoor and Asri 2022;Roy et al 2022;Sarkar et al 2023) have studied the basic properties of CKC distribution as well as the propagation of nonlinear waves in plasma system comprising of the CKC distributed particles. The combined effects of Kappa distribution and Cairns distribution as a form of non-Maxwellian distribution have been introduced by Aoutou et al (2008).…”

We have studied the formation of arbitrary amplitude ion-acoustic solitary structures using Sagdeev pseudo-potential approach in an unmagnetized dusty plasma system in the absence of collision whose constituents are combined Kappa-Cairns distributed electrons, negative-charged stationary dust particulates and adiabatic warm ions. This system supports both positive and negative potential conventional solitons along with the coexistence of these two solitons, double layers and supersolitons of negative polarity. Different types of solitary structures along with the impacts of the plasma parameters, viz., Mach number, suprathermal parameter and nonthermal parameter, of this system on the amplitude of these structures have been investigated by plotting the pseudo-potential with respect to the electrostatic potential. The formation of supersoliton after the formation of soliton has been illustrated using the mechanical analogy of phase portraits. The transition of soliton to supersoliton and soliton to double layer has been illustrated.
