Exact solutions for magnetic annihilation in curvilinear geometry
arXiv:physics/0212017 · doi:10.1016/S0375-9601(02)01174-X
Abstract
New exact solutions of the steady and incompressible 2D MHD equations in polar coordinates are presented. The solutions describe the process of reconnective magnetic annihilation in a curved current layer. They are particularly interesting for modeling magnetic reconnection in solar flares caused by the interaction of three photospheric magnetic sources.
