Exact solutions for magnetic annihilation in curvilinear geometry
  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.
