Reconstructing Highly-twisted Magnetic Fields
Victor M. Demcsak, Michael S. Wheatland, Alpha Mastrano +1
We investigate the ability of a nonlinear force-free code to calculate highly-twisted magnetic field configurations using the Titov and Démoulin (1999) equilibrium field as a test…
Self-consistent Nonlinear Force-free Field Reconstruction from Weighted Boundary Conditions
Alpha Mastrano, Kai E. Yang, Michael S. Wheatland
Vector magnetogram data are often used as photospheric boundary conditions for force-free coronal magnetic field extrapolations. In general, however, vector magnetogram data are no…
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…
