Dynamic topology and flux rope evolution during non-linear tearing of 3D null point current sheets

Simulated flux-rope evolution during non-inductive startup in Pegasus

Magnetic flux ropes produced during non-inductive startup of the Pegasus Toroidal Experiment [Eidietis N W, et al., 2007 J. Fusion Energy 26 43] are simulated with nonlinear magnetohydrodynamic (MHD) and two-fluid plasma models. A single injector is represented by a localized source-density for magnetic helicity and thermal energy. Results show development of a hollow tokamak-like profile from ...

Substorm Topology in the Ionosphere and Magnetosphere during a Flux Rope Event in the Magnetotail

substorms since the early models of Schindler (1974) and On August 13, 2002, at ~ 2300 UT, about 10 min “plasmoids”, played a major role in transporting the after a substorm intensification, Cluster observes a flux substorm energy antisunwards. The minimum energy rope in the central magnetotail, followed by a localised state of such helical magnetic field structures is fast flow event about one...

Magnetic Flux Topology of 2D Point Dipoles

Magnetic fields exhibit higher-order, nonlinear singularities in the form of point-dipole singularities. In addition, due to absence of divergence, they feature only a subset of invariant structures from traditional vector field topology. For magnetic fields of sets of point dipoles—widely present in physics and often used as an approximation—we present a technique revealing the topology of mag...
