Magnetic Null Reconnection
In 3D reconnection may occur both at locations where the magnetic field is non-
zero and in locations where the magnetic field locally vanishes - magnetic null
points. From simple kinematic investigations it has been found that
reconnection may occur in three different way involving magnetic null points -
Spine, Fan and Separator reconnection. Until now no one have fully understood
the way that these process evolves. A number of numerical experiments have
therefore been conducted to start investigating the dynamical properties of the
different types of reconnection. These show that 3D null reconnection in many
ways are very different from the well know 2D reconnection. There is still a
long way to go before we understand the process that determines the dynamics of
the reconnection process in nulls. The numerical experiments that we have made
until now have only scratch the surface...
