The European Solar Telescope
C. Quintero Noda, R. Schlichenmaier, L. R. Bellot Rubio +14
The European Solar Telescope (EST) is a project aimed at studying the magnetic connectivity of the solar atmosphere, from the deep photosphere to the upper chromosphere. Its design…
Studying the transfer of magnetic helicity in solar active regions with the connectivity-based helicity flux density method
K. Dalmasse, E. Pariat, G. Valori +2
In the solar corona, magnetic helicity slowly and continuously accumulates in response to plasma flows tangential to the photosphere and magnetic flux emergence through it. Analyzi…
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…
Magnetic field in atypical prominence structures: Bubble, tornado and eruption
P. J. Levens, B. Schmieder, A. López Ariste +3
Spectropolarimetric observations of prominences have been obtained with the THEMIS telescope during four years of coordinated campaigns. Our aim is now to understand the conditions…
A confined flare above filaments
K. Dalmasse, R. Chandra, B. Schmieder +1
We present the dynamics of two filaments and a C-class flare observed in NOAA 11589 on 2012 October 16. We used the multi-wavelength high-resolution data from SDO, as well as THEMI…
Photospheric Injection of Magnetic Helicity: Connectivity--based Flux Density Method
K. Dalmasse, E. Pariat, P. Démoulin +1
Magnetic helicity quantifies how globally sheared and/or twisted is the magnetic field in a volume. This quantity is believed to play a key role in solar activity due to its conser…
