Can We Improve the Preprocessing of Photospheric Vector Magnetograms by the Inclusion of Chromospheric Observations?
T. Wiegelmann, J. K. Thalmann, C. J. Schrijver +2
The solar magnetic field is key to understanding the physical processes in the solar atmosphere. Nonlinear force-free codes have been shown to be useful in extrapolating the corona…
First Stereoscopic Coronal Loop Reconstructions from Stereo Secchi Images
L. Feng, B. Inhester, S. K. Solanki +4
We present the first reconstruction of the three-dimensional shape of magnetic loops in an active region from two different vantage points based on simultaneously recorded images.…
Nonlinear force-free magnetic field extrapolations: comparison of the Grad-Rubin and Wheatland-Sturrock-Roumeliotis algorithm
B. Inhester, T. Wiegelmann
We compare the performance of two alternative algorithms which aim to construct a force-free magnetic field given suitable boundary conditions. For this comparison, we have impleme…
Segmentation of Loops from Coronal EUV Images
B. Inhester, L. Feng, T. Wiegelmann
We present a procedure which extracts bright loop features from solar EUV images. In terms of image intensities, these features are elongated ridge-like intensity maxima. To discri…
Preprocessing of Hinode/SOT vector magnetograms for nonlinear force-free coronal magnetic field modelling
T. Wiegelmann, J. K. Thalmann, C. J. Schrijver +2
The solar magnetic field is key to understanding the physical processes in the solar atmosphere. Nonlinear force-free codes have been shown to be useful in extrapolating the corona…
Hanle Effect Diagnostics of the Coronal Magnetic Field - A Test Using Realistic Magnetic Field Configurations
N. -E. Raouafi, S. K. Solanki, T. Wiegelmann
Our understanding of coronal phenomena, such as coronal plasma thermodynamics, faces a major handicap caused by missing coronal magnetic field measurements. Several lines in the UV…
