On measuring divergence for magnetic field modeling
S. A. Gilchrist, K. D. Leka, G. Barnes +2
A physical magnetic field has a divergence of zero. Numerical error in constructing a model field and computing the divergence, however, introduces a finite divergence into these c…
Relative Magnetic Helicity Based on a Periodic Potential Field
Kai E. Yang, Michael S. Wheatland, Stuart A. Gilchrist
Magnetic helicity is conserved under ideal magnetohydrodynamics (MHD) and quasi-conserved even under a resistive process. The standard definition for magnetic helicity cannot be ap…
Vortex and sink flows in eruptive flares as a model for coronal implosions
Francesco P. Zuccarello, Guillaume Aulanier, Jaroslav Dudík +3
Eruptive flares are sudden releases of magnetic energy that involve many phenomena, several of which can be explained by the standard 2D flare model and its realizations in three-d…
