Additivity of relative magnetic helicity in finite volumes
Gherardo Valori, Pascal Démoulin, Etienne Pariat +3
Relative magnetic helicity is conserved by magneto-hydrodynamic evolution even in the presence of moderate resistivity. For that reason, it is often invoked as the most relevant co…
Energy and helicity fluxes in line-tied eruptive simulations
Luis Linan, Étienne Pariat, Guillaume Aulanier +2
Based on a decomposition of the magnetic field into potential and nonpotential components, magnetic energy and relative helicity can both also be decomposed into two quantities: po…
Magnetic helicity budget of solar active regions prolific of eruptive and confined flares
J. K. Thalmann, K. Moraitis, L. Linan +3
We compare the coronal magnetic energy and helicity of two solar active regions (ARs), prolific in major eruptive (AR~11158) and confined (AR~12192) flaring, and analyze the potent…
Magnetic helicity and eruptivity in active region 12673
K. Moraitis, X. Sun, E. Pariat +1
Context. In September 2017 the largest X-class flare of Solar Cycle 24 occurred from the most active region (AR) of this cycle, AR 12673. The AR attracted much interest because of…
Time variations of the non-potential and volume-threading magnetic helicities
Luis Linan, Étienne Pariat, Kostas Moraitis +2
Relative magnetic helicity is a gauge invariant quantity suitable for the study of the magnetic helicity content of heliospheric plasmas. Relative magnetic helicity can be decompos…
Threshold of non-potential magnetic helicity ratios at the onset of solar eruptions
Francesco P. Zuccarello, Etienne Pariat, Gherardo Valori +1
The relative magnetic helicity is a quantity that is often used to describe the level of entanglement of non-isolated magnetic fields, such as the magnetic field of solar active re…
