Catastrophe versus instability for the eruption of a toroidal solar magnetic flux rope
B. Kliem, J. Lin, T. G. Forbes +2
The onset of a solar eruption is formulated here as either a magnetic catastrophe or as an instability. Both start with the same equation of force balance governing the underlying…
The Evolution of Writhe in Kink-Unstable Flux Ropes and Erupting Filaments
Tibor Torok, Bernhard Kliem, Mitchell A. Berger +3
The helical kink instability of a twisted magnetic flux tube has been suggested as a trigger mechanism for solar filament eruptions and coronal mass ejections (CMEs). In order to i…
Distribution of Electric Currents in Solar Active Regions
Tibor Török, James E. Leake, Viacheslav S. Titov +6
There has been a long-lasting debate on the question of whether or not electric currents in solar active regions are neutralized. That is, whether or not the main (or direct) coron…
Homologous Flares and Magnetic Field Topology in Active Region NOAA 10501 on 20 November 2003
R. Chandra, B. Schmieder, C. H. Mandrini +4
We present and interpret observations of two morphologically homologous flares that occurred in active region (AR) NOAA 10501 on 20 November 2003. Both flares displayed four homolo…
Testing magnetofrictional extrapolation with the Titov-Démoulin model of solar active regions
G. Valori, B. Kliem, T. Török +1
We examine the nonlinear magnetofrictional extrapolation scheme using the solar active region model by Titov and Démoulin as test field. This model consists of an arched, line-tied…
