Abstract

Steadily propagating monopole vortex solutions to the ηi-mode equations are investigated. A general condition for non-linear vortex solutions to be steadily propagating is derived by demanding that their velocity is outside the regime of linear-wave propagation. The velocity of the vortex is determined by the ratio of the pressure perturbation and the electrostatic potential. Numerical studies show that such vortices generally emerge from localized initial conditions. A new type of vortex interaction is also revealed.
