Change ratios of magnetic helicity and magnetic free energy during major solar flares
Quan Wang, Mei Zhang, Shangbin Yang +2
Magnetic helicity is an important concept in solar physics, with a number of theoretical statements pointing out the important role of magnetic helicity in solar flares and coronal…
Comparison of Two Methods for Calculating Magnetic Helicity in the Solar Corona
Quan Wang, Shangbin Yang, Mei Zhang +1
Duo to the large magnetic Reynolds number, the magnetic helicity originating from the solar interior can be carried away through the photosphere into the corona. However, the relat…
A White-light Flare Powered by Magnetic Reconnection in the Lower Solar Atmosphere
Yongliang Song, Hui Tian, Xiaoshuai Zhu +3
White-light flares (WLFs), first observed in 1859, refer to a type of solar flares showing an obvious enhancement of the visible continuum emission. This type of enhancement often…
Activity Analyses for Solar-type Stars Observed with Kepler. II. Magnetic Feature Versus Flare Activity
Han He, Huaning Wang, Mei Zhang +3
The light curves of solar-type stars present both periodic fluctuation and flare spikes. The gradual periodic fluctuation is interpreted as the rotational modulation of magnetic fe…
Magnetic Helicity Reversals in a Cyclic Convective Dynamo
Mark S. Miesch, Mei Zhang, Kyle C. Augustson
We investigate the role of magnetic helicity in promoting cyclic magnetic activity in a global, 3D, magnetohydrodynamic (MHD) simulation of a convective dynamo. This simulation is…
On the relationship between sunspot structure and magnetic field changes associated with solar flares
Yongliang Song, Mei Zhang
Many previous studies have shown that magnetic fields as well as sunspot structures present rapid and irreversible changes associated with solar flares. In this paper we first use…
