Current singularities at finitely compressible three-dimensional magnetic null points
(2005)The formation of current singularities at line-tied two- and three-dimensional (2D and 3D, respectively) magnetic null points in a nonresistive magnetohydrodynamic environment is explored. It is shown that, despite the ... -
Current singularities in line-tied three-dimensional magnetic fields
(IOP PUBLISHING LTD, 2014-06-20)This paper considers the current distributions that derive from finite amplitude perturbations of line-tied magnetic fields comprising hyperbolic field structures. The initial equilibrium on which we principally focus is ... -
Dynamic three-dimensional reconnection in a separator geometry with two null points
(2006-05)The dynamic behavior of disturbances in the vicinity of a pair of magnetically connected three-dimensional null points is examined. The aim is to investigate how nonlinear disturbances lead to strong localized currents ... -
Lagrangian relaxation schemes for calculating force-free magnetic fields, and their limitations
(IOP Publishing Ltd, 2009)Force-free magnetic fields are important in many astrophysical settings. Determining the properties of such force-free fields—especially smoothness and stability properties—is crucial to understanding many key phenomena ...
