Magnetic helicity estimations in models and observations of the solar magnetic field. Part IV: Application to solar observations
J. K. Thalmann, M. K. Georgoulis, Y. Liu +8
In this ISSI-supported series of studies on magnetic helicity in the Sun, we systematically implement different magnetic helicity calculation methods on high-quality solar magnetog…
The causes of quasi-homologous CMEs
Lijuan Liu, Yuming Wang, Rui Liu +8
In this paper, we identified the magnetic source locations of 142 quasi- homologous (QH) coronal mass ejections (CMEs), of which 121 are from solar cycle (SC) 23 and 21 from SC 24.…
Arcade Implosion Caused by a Filament Eruption in a Flare
Juntao Wang, P. J. A. Simoes, L. Fletcher +3
Coronal implosions - the convergence motion of plasmas and entrained magnetic field in the corona due to a reduction in magnetic pressure - can help to locate and track sites of ma…
Temporal and spatial relationship of flare signatures and the force-free coronal magnetic field
Julia K. Thalmann, Astrid M. Veronig, Yang Su
We investigate the plasma and magnetic environment of active region NOAA 11261 on 2 August 2011 around a GOES M1.4 flare/CME (SOL2011-08-02T06:19). We compare coronal emission at (…
The Influence of Spatial Resolution on Nonlinear Force-Free Modeling
M. L. DeRosa, M. S. Wheatland, K. D. Leka +11
The nonlinear force-free field (NLFFF) model is often used to describe the solar coronal magnetic field, however a series of earlier studies revealed difficulties in the numerical…
Force-free field modeling of twist and braiding-induced magnetic energy in an active-region corona
J. K. Thalmann, S. K. Tiwari, T. Wiegelmann
The theoretical concept that braided magnetic field lines in the solar corona may dissipate a sufficient amount of energy to account for the brightening observed in the active-regi…
