Reconstruction of Coronal Magnetic Fields Using a Poloidal-Toroidal Representation
Sibaek Yi, G. S. Choe, Kyung-Suk Cho +2
A new method for reconstruction of coronal magnetic fields as force-free fields (FFFs) is presented. Our method employs poloidal and toroidal functions to describe divergence-free…
The toroidal field surfaces in the standard poloidal-toroidal representation of magnetic field
Sibaek Yi, G. S. Choe
The representation of magnetic field as a sum of a toroidal field and a poloidal field has not rarely been used in astrophysics, particularly in relation to stellar and planetary m…
Coronal Dynamic Activities in the Declining Phase of a Solar Cycle
Minhwan Jang, T. N. Woods, Sunhak Hong +1
It has been known that some solar activity indicators show a double-peak feature in their evolution through a solar cycle, which is not conspicuous in sunspot number. In this lette…
Magnetohydrodynamic Simulation of the X2.2 Solar Flare on 2011 February 15: II. Dynamics Connecting the Solar Flare and the Coronal Mass Ejection
S. Inoue, K. Hayashi, T. Magara +2
We clarify a relationship of the dynamics of a solar flare and a growing Coronal Mass Ejection (CME) by investigating the dynamics of magnetic fields during the X2.2-class flare ta…
Magnetohydrodynamic Simulation of the X2.2 Solar Flare on 2011 February 15: I. Comparison with the Observations
S. Inoue, K. Hayashi, T. Magara +2
We performed a magnetohydrodynamic (MHD) simulation using a nonlinear force-free field (NLFFF) in solar active region 11158 to clarify the dynamics of an X2.2-class solar flare. We…
Magnetic Structure Producing X- and M-Class Solar Flares in Solar Active Region 11158
S. Inoue, K. Hayashi, D. Shiota +2
We study the three-dimensional magnetic structure of solar active region 11158, which produced one X-class and several M-class flares on 2011 February 1316. We focus on the magn…
