Energetics of kinetic reconnection in a three-dimensional null-point cluster.
We perform three-dimensional particle-in-cell simulations of magnetic reconnection with multiple magnetic null points. Magnetic field energy conversion into kinetic energy is about five times higher than in traditional Harris sheet configuration. More than 85% of initial magnetic field energy is transferred to particle energy during 25 reversed ion cyclofrequencies. Magnetic reconnection in the...
متن کاملThree-Dimensional Magnetic Reconnection
The importance of magnetic reconnection as an energy release mechanism in many solar, stellar, magnetospheric and astrophysical phenomena has long been recognised. Reconnection is the only mechanism by which magnetic fields can globally restructure, enabling them to access a lower energy state. Over the past decade, there have been some major advances in our understanding of threedimensional re...

متن کاملIs null - point reconnection important for solar flux emergence ?
The role of null-point reconnection in a 3D numerical MHD model of solar emerging flux is investigated. The model consists of a twisted magnetic flux tube rising through a stratified convection zone and atmosphere to interact and reconnect with a horizontal overlying magnetic field in the atmosphere. Null points appear as the reconnection begins and persist throughout the rest of the emergence,...
متن کاملManifold reconnection in chaotic regimes
Two-dimensional nonmonotonic conservative maps are recognized to be of relevance in modeling a number of nonlinear systems, for instance, laser acceleration of charged particles @1–6#, and the nonlinear flow of magnetic field lines in fusion machines such as tokamaks and others @7,8#. As opposed to more traditional monotonic versions, nonmonotonic maps are characterized by frequency curves that...
