Relative Alpha in the Magneto-Hydro-Dynamics (MHD) with open magnetic field boundary and its application to the solar eruption
Shangbin Yang, Joerg Buechner, Jean Carlo Santos +2
An instability criterion in the MHD with the open boundary of magnetic field is proposed in this paper. We use a series of linear force-free extrapolation field, in which the norma…

Comparison of Relative Magnetic Helicity Flux Calculation Results Based on the Line-of-Sight Magnetograms of ASO-S/FMG and SDO/HMI
Shangbin Yang, Suo Liu, Jiangtao Su +1
Magnetic helicity is a key geometrical parameter to describe the structure and evolution of solar coronal magnetic fields. The accumulation of magnetic helicity is correlated with…
