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…

Slippage of Jets Explained by the Magnetic Topology of NOAA Active Region 12035

R. Joshi, B. Schmieder, R. Chandra +3

In this study, we present the investigation of eleven recurring solar jets originated from two different sites (site 1 and site 2) close to each other (~ 11 Mm) in the NOAA active…

Expanding and Contracting Coronal Loops as Evidence of Vortex Flows Induced by Solar Eruptions

J. Dudík, F. P. Zuccarello, G. Aulanier +2

Eruptive solar flares were predicted to generate large-scale vortex flows at both sides of the erupting magnetic flux rope. This process is analogous to a well-known hydrodynamic p…

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…

The transition from eruptive to confined flares in the same active region

F. P. Zuccarello, R. Chandra, B. Schmieder +2

Solar flares are sudden and violent releases of magnetic energy in the solar atmosphere that can be divided in eruptive flares, when plasma is ejected from the solar atmosphere, re…

Critical decay index at the onset of solar eruptions

F. P. Zuccarello, G. Aulanier, S. A. Gilchrist

Magnetic flux ropes are topological structures consisting of twisted magnetic field lines that globally wrap around an axis. The torus instability model predicts that a magnetic fl…

Observational evidence of torus instability as trigger mechanism for coronal mass ejections: the 2011 August 4 filament eruption

Francesco P. Zuccarello, Daniel B. Seaton, Marilena Mierla +4

Solar filaments are magnetic structures often observed in the solar atmosphere and consist of plasma that is cooler and denser than their surroundings. They are visible for days --…
