Back Reaction of the Untwisting Solar Corona Scars Sunspots
Chen Xing, Xin Cheng, Guillaume Aulanier +1
The evolution of magnetic fields in the tenuous solar corona is predominantly governed by the motions of the underlying dense photosphere. Despite, coronal magnetic restructuring d…
Unprecedent fast winking of solar flares triggered by bursty magnetic reconnection
Ting Li, Xuchun Duan, Yijun Hou +13
Flare ribbons form as a result of energy deposition associated with particles accelerated in low layers of the solar atmosphere. The fine-scale structures of flare ribbons, also ca…
White paper on the relevance of the European Solar Telescope (EST) for the French heliophysics
E. Pariat, Q. Noraz, B. Perri +61
The project of the European Solar Telescope aims to provide a state-of-the art infrastructure to study the Sun and its interactions with Earth and the heliosphere. This 4.2m apertu…
Chromosphere of the quiet sun: II. Atmospheric response to small-scale magnetic flux emergence
Quentin Noraz, Mats Carlsson, Guillaume Aulanier
Coupling between the photosphere, chromosphere and corona in the quiet Sun (QS) is governed by a complex interplay between magnetic structuring, heating, mass loading, and radiativ…
Flux rope formation through flux cancellation of sheared coronal arcades in a 3D convectively-driven MHD simulation
Sondre Vik Furuseth, Guillaume Aulanier
Context. Space weather and its potential negative consequences for life on Earth has received increasing attention in recent decades. Particularly predicting CME onset has become i…
Shock-induced magnetic reconnection driving Ellerman bomb emission and a spicule
Mats Ola Sand, Quentin Noraz, Guillaume Aulanier +3
The mechanism that forms dynamic type II spicules has remained elusive for many years. Their dynamical behaviour has long been linked to magnetic reconnection, yet no conclusive ev…
Active chromospheric fibril singularity: Coordinated observations from Solar Orbiter, SST, and IRIS
Reetika Joshi, Luc Rouppe van der Voort, Guillaume Aulanier +6
The fine structures of the solar chromosphere, driven by photospheric motions, play a crucial role in the dynamics of solar magnetic fields. Many have been already identified such…
Chromosphere of the quiet sun -- I. Shock and current-sheet dynamics and heating
Quentin Noraz, Mats Carlsson, Guillaume Aulanier
The solar chromosphere is a crucial interface between the solar interior and its interplanetary environment, regulating how energy is locally deposited into heat and transported in…
On the occurrence of thermal non-equilibrium in coronal loops
C. Froment, F. Auchère, Z. Mikić +5
Long-period EUV pulsations, recently discovered to be common in active regions, are understood to be the coronal manifestation of thermal non-equilibrium (TNE). The active regions…
Long-Period Intensity Pulsations in Coronal Loops Explained by Thermal Non-Equilibrium Cycles
Clara Froment, Frédéric Auchère, Guillaume Aulanier +4
In solar coronal loops, thermal non-equilibrium (TNE) is a phenomenon that can occur when the heating is both highly-stratified and quasi-constant. Unambiguous observational identi…
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…
Distribution of Electric Currents in Solar Active Regions
Tibor Török, James E. Leake, Viacheslav S. Titov +6
There has been a long-lasting debate on the question of whether or not electric currents in solar active regions are neutralized. That is, whether or not the main (or direct) coron…
