| heal.abstract | The cat-eyes steady-state solution in the framework of hydrodynamics describing an infinite row of identical vortices is extended to the magnetohydrodynamic equilibrium equation with incompressible flow of arbitrary direction. The extended solution covers a variety of equilibria including one- and two-dimensional generalized force-free and Harris-sheet configurations which are preferable to those usually employed as initial states in reconnection studies. Although for the extended cat-eyes equilibrium the vortex shape is not affected by the magnetic field, the flow in conjunction with the equilibrium nonlinearity has a strong impact on isobaric surfaces by forming pressure islands located within the cat-eyes vortices. More importantly, a magnetic-field-aligned flow of experimental fusion relevance and the flowshear have significant stabilizing effects in the region of the pressure islands. The stable region is enhanced by an external axial ('toroidal') magnetic field. | en |
