     electrostatic solitary structures are studied in uniform and nonuniform magnetoplasmas with superthermal electrons. in the linear analysis, the differences in the acoustic frequencies for maxwellian, cairns, and kappa distributed electrons for both homogeneous and inhomogeneous plasmas are highlighted and discussed. it is shown that using the linear dispersion relation, nonlinear zakharov-kuznetsov (zk) equation can be derived both for the homogeneous and inhomogeneous magnetoplasmas. the solution of the zk equation is presented using the tangent hyperbolic method. it is found that the increasing magnetic field and the angle of propagation enhances the amplitude whereas the increasing number density mitigates the amplitude of the acoustic drift solitary wave. furthermore, it is observed that the amplitude of the solitary structure is maximum for cairns, intermediate for maxwellian, and minimum for the kappa distributed electrons. the results presented in this paper may be beneficial to understand the formation of electrostatic drift solitary waves in planetary environments where the nonthermal population of electrons are observed by various satellite missions.
