Gradual Inflation of Active-Region Coronal Arcades Building up to Coronal Mass Ejections
Rui Liu, Chang Liu, Sung-Hong Park +1
The pre-CME structure is of great importance to understanding the origin of CMEs, which, however, has been largely unknown for CMEs originating from active regions. In this paper,…
Time Evolution of Coronal Magnetic Helicity in the Flaring Active Region NOAA 10930
Sung-Hong Park, Jongchul Chae, Ju Jing +2
To study the three-dimensional (3D) magnetic field topology and its long-term evolution associated with the X3.4 flare of 2006 December 13, we investigate the coronal relative magn…
Productivity of Solar Flares and Magnetic Helicity Injection in Active Regions
Sung-Hong Park, Jongchul Chae, Haimin Wang
The main objective of this study is to better understand how magnetic helicity injection in an active region is related to the occurrence and intensity of solar flares. We therefor…
The variation of relative magnetic helicity around major flares
Sung-Hong Park, Jeongwoo Lee, Gwang-Son Choe +5
We have investigated the variation of magnetic helicity over a span of several days around the times of 11 X-class flares which occurred in seven active regions (NOAA 9672, 10030,…
