Substructure of Quiet Sun Bright Points
Aleksandra Andic, Jongchul Chae, Phillip R. Goode
Since photospheric bright points (BPs) were first observed, there has been a question as to how are they structured. Are they just single flux tubes or a bundle of the flux-tubes?…
The Formation of a Magnetic Channel by the Emergence of Current-carrying Magnetic Fields
Eun-Kyung Lim, Jongchul Chae, Ju Jing +2
A magnetic channel - a series of polarity reversals separating elongated flux threads with opposite polarities - may be a manifestation of a highly non-potential magnetic configura…
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…
Oscillatory behavior in the quiet Sun observed with the New Solar Telescope
A. ~Andic, P. R. Goode, J. Chae +4
Surface photometry of the quiet Sun has achieved an angular resolution of with the New Solar Telescope at Big Bear Solar Observatory revealing that a disproportionate fracti…
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,…
