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…
Evolution of A Magnetic Flux Rope toward Eruption
Wensi Wang, Chunming Zhu, Jiong Qiu +3
It is well accepted that a magnetic flux rope (MFR) is a critical component of many coronal mass ejections (CMEs), yet how it evolves toward eruption remains unclear. Here we inves…
Extremely Large Extreme-ultraviolet Late Phase Powered by Intense Early Heating in a Non-eruptive Solar Flare
Yu Dai, Mingde Ding, Weiguo Zong +1
We analyzed and modeled an M1.2 non-eruptive solar flare on 2011 September 9. The flare exhibits a strong late-phase peak of the warm coronal emissions (3~MK) of extreme-ultr…
Observationally quantified reconnection providing a viable mechanism for active region coronal heating
Kai E. Yang, Dana W. Longcope, M. D. Ding +1
The heating of the Sun's corona has been explained by several different mechanisms including wave dissipation and magnetic reconnection. While both have been shown capable of suppl…
