Abstract
An analytical approach is employed to investigate the coupled drift and ion acoustic solitary structures in a bi-ion ionospheric oxygen-hydrogen (O-H) plasma having density and temperature inhomogeneities, as well as Kappa distributed electrons. We derive the nonlinear partial differential equation, which is then turned into a pseudo-potential energy equation. With the help of necessary conditions for the formation of solitons, we get the profiles of pseudo-potential and solitary pulses by employing the Sagdeev truncated method. It is shown that both rarefactive (dip) and compressive (hump) solitary structures are possible in a plasma having both density and temperature gradients. The dip structures are supersonic in nature, and hump structures are subsonic as reported by Freja satellite mission earlier.
