Changes of Magnetic Energy and Helicity in Solar Active Regions from Major Flares

Yang Liu, Brian T. Welsch, Gherardo Valori +5

Magnetic free energy powers solar flares and coronal mass ejections (CMEs), and the buildup of magnetic helicity might play a role in the development of unstable structures that su…

Solar Flares and Magnetic Helicity

Shin Toriumi, Sung-Hong Park

Solar flares and coronal mass ejections are the largest energy release phenomena in the current solar system. They cause drastic enhancements of electromagnetic waves of various wa…

Magnetic Helicity Flux across Solar Active Region Photospheres: II. Association of Hemispheric Sign Preference with Flaring Activity during Solar Cycle 24

Sung-Hong Park, K. D. Leka, Kanya Kusano

In our earlier study of this series (Park et al. 2020, Paper I), we examined the hemispheric sign preference (HSP) of magnetic helicity flux across photospheric surfaces of…

Data-driven MHD simulation of successive solar plasma eruptions

Takafumi Kaneko, Sung-Hong Park, Kanya Kusano

Solar flares and plasma eruptions are sudden releases of magnetic energy stored in the plasma atmosphere. To understand the physical mechanisms governing their occurrences, three-d…
