Abstract ：Nonlinear ion-acoustic solitary wave structures in collisionless, non-relativistic, homogenous, magneto-rotating plasma, in which the electron species follow the kappa distribution function, are studied. The Korteweg-de Vries (KdV) equation is derived by using the reductive perturbation method, and the effects of different plasma parameters on the obliquely propagating nonlinear solitary wave structures in the magneto-rotating plasma are presented. It is noticed that the spectral index parameter κ significantly modifies the nonlinear wave structure.
