The Magnetic Field in the Solar Atmosphere
Thomas Wiegelmann, Julia K. Thalmann, Sami K. Solanki
This publication provides an overview of magnetic fields in the solar atmosphere with the focus lying on the corona. The solar magnetic field couples the solar interior with the vi…
Three-dimensional Magnetic Restructuring in Two Homologous Solar Flares in the Seismically Active NOAA AR 11283
Chang Liu, Na Deng, Jeongwoo Lee +6
We carry out a comprehensive investigation comparing the three-dimensional magnetic field restructuring, flare energy release, and the helioseismic response, of two homologous flar…
Effect of Size of the Computational Domain on Spherical Nonlinear Force-Free Modeling of Coronal Magnetic Field Using SDO/HMI Data
Tilaye Tadesse, Thomas Wiegelmann, Peter MacNeice
The solar coronal magnetic field produces solar activity, including extremely energetic solar flares and coronal mass ejections (CMEs). Knowledge of the structure and evolution of…
Quasi-Static 3D-Magnetic Field Evolution in Solar Active Region NOAA 11166 Associated with X1.5 Flare
P. Vemareddy, T. Wiegelmann
We study the quasi-static evolution of coronal magnetic fields constructed from the Non Linear Force Free Field (NLFFF) approximation aiming to understand the relation between the…
Statistical study of free magnetic energy and flare productivity of solar active regions
J. T. Su, J. Jing, S. Wang +2
Photospheric vector magnetograms from Helioseismic and Magnetic Imager on board the Solar Dynamic Observatory are utilized as the boundary conditions to extrapolate both non-linear…
Temporal Evolution of the Magnetic Topology of the NOAA Active Region 11158
Jie Zhao, Hui Li, Etienne Pariat +3
We studied the temporal evolution of the magnetic topology of the active region (AR) 11158 based on the reconstructed three-dimensional magnetic fields in the corona. The \nlfff\ e…
