Magnetohydrodynamic coronal modelling with high-fidelity magnetograms
Haopeng Wang, Stefaan Poedts, Wensi Wang +16
To resolve coronal structures in detail, it is essential to constrain the coronal model using high-fidelity magnetograms with minimal smoothing. In this paper, we improve the numer…
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…
COCONUT: Toward practical time-evolving Sun-to-Earth magnetohydrodynamic modeling
Haopeng Wang, Stefaan Poedts, Andrea Lani +16
Due to computational efficiency and numerical stability limitations, coronal simulations constrained by static magnetograms are typically performed first and then used to drive inn…
MHD modeling of magnetic flux evolution around solar maximum by the coronal model COCONUT
Haopeng Wang, Stefaan Poedts, Andrea Lani +15
In this paper, we simulate the magnetic flux evolution at different heliocentric distances during two solar-maximum Carrington rotations (CRs) using the time-evolving coronal magne…
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…
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…
Avalanches in Magnetohydrodynamical simulations
Henri Lamarre, Paul Charbonneau, Quentin Noraz +5
Scale invariance is a hallmark of many natural systems, including solar flares, where energy release spans a vast range of scales. Recent computational advances, at the level of bo…
Decomposing wave activity in the solar atmosphere: Shocks, jets and swirls in the quiet Sun
George Cherry, Boris Gudiksen, Adam J. Finley +1
Context. There remains much mystery about how or if wave-energy in the photosphere can be transferred sufficiently upwards through the solar atmosphere to contribute to coronal hea…
Magnetic activity evolution of solar-like stars: II. -Ro evolution of Kepler main-sequence targets
Savita Mathur, Angela R. G. Santos, Zachary R. Claytor +16
There is now a large sample of stars observed by the Kepler satellite with measured rotation periods and photometric activity index . We use this data, in conjunction w…
Global Turbulent Solar Convection: a Numerical Path Investigating Key Force Balances in the context of the Convective Conundrum
Quentin Noraz, Allan Sacha Brun, Antoine Strugarek
Understanding solar turbulent convection and its influence on differential rotation has been a challenge over the past two decades. Current models often overestimate giant convecti…
Measuring stellar surface rotation and activity with the PLATO mission -- I. Strategy and application to simulated light curves
S. N. Breton, A. F Lanza, S. Messina +20
The Planetary Transits and Oscillations of stars mission (PLATO) will allow us to measure surface rotation and monitor photometric activity of tens of thousands of main sequence so…
Magnetochronology of solar-type star dynamos
Quentin Noraz, Allan Sacha Brun, Antoine Strugarek
Aims. In this study, we analyse the magnetic field properties of a set of 15 global magnetohydrodynamics (MHD) simulations of solar-type star dynamos conducted using the ASH code.…
Dynamics of solar large-scale flows
Hideyuki Hotta, Yuto Bekki, Laurent Gizon +2
The Sun's axisymmetric large-scale flows, differential rotation and meridional circulation, are thought to be maintained by the influence of rotation on the thermal-convective moti…
Hunting for anti-solar differentially rotating stars using the Rossby number -- An application to the Kepler field
Quentin Noraz, Sylvain N. Breton, Allan Sacha Brun +5
Anti-solar differential rotation profiles have been found for decades in numerical simulations of convective envelopes of solar-type stars. These profiles are characterized by a sl…
Powering Stellar Magnetism: Energy Transfers in Cyclic Dynamos of Sun-like Stars
Allan Sacha Brun, Antoine Strugarek, Quentin Noraz +5
We use the ASH code to model the convective dynamo of solar-type stars. Based on a series of 15 3-D MHD simulations spanning 4 bins in rotation and mass, we show what mechanisms ar…
