TY - CHAP T1 - Magnetic reconnection A1 - Priest,E. R. A1 - Pontin,D. I. AU - Priest,E. R. AU - Pontin,D. I. PB - Kluwer Academic CY - Dordrecht PY - 2004 Y1 - 2004 N2 - Magnetic reconnection is a fundamental process in a cosmic plasma such as the solar corona, responsible for heating and for many dynamic phenomena. We here review briefly the basic theory of reconnection in two dimensions and then proceed to describe several features of the way it operates in three dimensions. These include a description of 3D null points, of 3D topology, and of spine, fan and separator reconnection. Also an account of new properties of 3D reconnection at an isolated diffusion region is given, including the fact that a unique field line velocity can no longer be defined and that field line connections change continuously while a field line is traversing the non-ideal region. A summary is given of the various ways in which the corona may be heated, including binary, separator and braiding reconnection, as well as heating by coronal tectonics. Finally, a summary is also given of reconnection processes in the Earth’s magnetosphere AB - Magnetic reconnection is a fundamental process in a cosmic plasma such as the solar corona, responsible for heating and for many dynamic phenomena.
