摘要：
Effects of superthermal electron on the features of nonlinear acoustic waves in unmagnetized collisionless ion pair plasma with superthermal electrons have been examined. The system equations are reduced in the form of the nonlinear Schrodinger equation. The rogue wave characteristics dependences on the ionic density ratio (v = n(-0)/n(+0)), ionic mass ratio (Q = m(+)/m(-)), and superthermality index (kappa) are investigated. It is worth mentioning that the results present in this work could be applicable in the Earth's ionosphere plasmas. (C) 2016 AIP Publishing LLC.
