“…Rather of influencing the frequency related to the appropriate length range, they often affect the development of mass density on vast time periods due to pressure gradients. IAWs form in both unmagnetized [1][2][3] and magnetized plasmas that are parallel to the magnetic field [4][5][6].…”

We study theoretically and numerically the nonlinear propagation of ion acoustic waves (IAWs) in plasma. The electrostatic potential in electron-ion (e-i) plasma is mimicked by the cylindrical Kadomtsev-Petviashvili (cKP) equation using the traditional reductive perturbation approach. By applying the direct integration technique, the soliton solution is obtained. The results of simulations carried out numerically show that the amplitude as well as width of the soliton solution are signicantly in uenced by the plasma parameters. The exploration of IAWs propagation in laboratory as well as space plasmas may benet from the current work.
