The dependence of the helicity bound of force-free magnetic fields on boundary conditions
Mei Zhang, Natasha Flyer
This paper follows up on a previous study showing that in an open atmosphere such as the solar corona the total magnetic helicity of a force-free field must be bounded and the accu…

Helicity Observation of Weak and Strong Fields
Mei Zhang
We report in this letter our analysis of a large sample of photospheric vector magnetic field measurements. Our sample consists of 17200 vector magnetograms obtained from January 1…

Magnetic Field Confinement in the Corona: The Role of Magnetic Helicity Accumulation
Mei Zhang, Natasha Flyer, Boon Chye Low
A loss of magnetic field confinement is believed to be the cause of coronal mass ejections (CMEs), a major form of solar activity in the corona. The mechanisms for magnetic energy…
