Testing predictors of eruptivity using parametric flux emergence simulations
Chloé Guennou, Etienne Pariat, Nicole Vilmer +1
Solar flares and coronal mass ejections (CMEs) are among the most energetic events in the solar system, impacting the near-Earth environment. Flare productivity is empirically know…
Magnetic Helicity Estimations in Models and Observations of the Solar Magnetic Field. Part III: Twist Number Method
Y. Guo, E. Pariat, G. Valori +7
We study the writhe, twist and magnetic helicity of different magnetic flux ropes, based on models of the solar coronal magnetic field structure. These include an analytical force-…
Flux rope, hyperbolic flux tube, and late EUV phases in a non-eruptive circular-ribbon flare
S. Masson, E. Pariat, G. Valori +4
We present a detailed study of a confined circular flare dynamics associated with 3 UV late phases in order to understand more precisely which topological elements are present and…
Relative magnetic helicity as a diagnostic of solar eruptivity
E. Pariat, J. E. Leake, G. Valori +3
The discovery of clear criteria that can deterministically describe the eruptive state of a solar active region would lead to major improvements on space weather predictions. Using…
Observational Evidence of Magnetic Reconnection for Brightenings and Transition Region Arcades in IRIS observations
Jie Zhao, Brigitte Schmieder, Hui Li +4
By using a new method of forced-field extrapolation, we study the emerging flux region AR 11850 observed by the Interface Region Imaging Spectrograph (IRIS) and Solar Dynamical Obs…
