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…
Sungrazer comets as analogs of star-planet magnetic interactions
L-S. Guité, A. Strugarek, A. J. Finley +5
Star-planet magnetic interactions (SPMIs) can transfer energy from an exoplanet to its host star via Alfvén waves when the planet orbits within a sub-Alfvénic stellar wind. Simil…
Energetics and Emission in a Simulated Solar Flare Initialised by a Non-Force Free Magnetic Field
W. Bate, M. Gordovskyy, A. Prasad +7
Solar flare simulations are commonly initialised using non-linear force free field (NLFF) extrapolations derived from photospheric vector magnetograms. However, the force free assu…
Chromospheric turbulence as a regulator of stellar wind mass flux
Munehito Shoda, Tom Van Doorsselaere, Allan Sacha Brun
The mass flux of solar and stellar winds is a key quantity for stellar evolution and space weather, yet its physical regulation mechanism remains an unsolved problem. In particular…
POP-CORN: Validation of a new coronal hole detection tool based on neural networks
K. H. P. Henadhira Arachchige, B. Perri, A. S. Brun
The properties and spatial distribution of large-scale structures of the solar corona determine the observed solar wind structure at 1 au. Coronal holes are a major source of fast…
Formation and rising phase of a flux rope through data-constrained simulations
M. V. Sieyra, A. Strugarek, A. Prasad +8
Context. Data-constrained models incorporate observed photospheric magnetic fields. However, due to the lack of magnetic field information in the rest of the solar atmosphere, mode…
