Polarity inversion line helicities and solar eruptivity
K. Moraitis, J. K. Thalmann
This work examines the relationship between solar eruptivity and the relative helicity that is contained around the polarity inversion line (PIL) of the magnetic field, along with…

Magnetic structure and asymmetric eruption of a 500 Mm filament rooted in weak-field regions
Stefan Purkhart, Astrid M. Veronig, Robert Jarolim +2
We performed a detailed analysis of the magnetic structure and asymmetric eruption of a large (about 500 Mm) inverse S-shaped filament partially located in AR 13229 on February 24,…

Conditioning of the solar corona due to large flares
Julia K. Thalmann, Manu Gupta, Astrid M. Veronig +1
We aim to better characterize the conditions of the solar corona, especially with respect to the occurrence of confined and eruptive flares. In this work, we model the coronal evol…
