Electron transport in a radiation-dominated plasma Application to solar corona brightenings
Roland Duclous, Vladimir Tikhonchuk, Marina Leboulanger +3
Bremsstrahlung scattering of fast electrons on ions can be enhanced by the microwave radiation present in the solar corona. It can account for the electron diffusive transport alon…
Can meridional flow variations explain the observed rising/declining phase asymmetry in the solar cycle?
Soumitra Hazra, Allan Sacha Brun, Laurene Jouve
Accurate prediction of the 11-year solar cycle remains a major challenge in solar physics and is important for space weather forecasting. A persistent property of the cycle is its…
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…
A prolific solar flare factory. Nearly continuous monitoring of an active region nest with Solar Orbiter
Adam J. Finley, Allan Sacha Brun, Antoine Strugarek +1
The properties of active region nests, which are locations on the Sun with recurring flux emergence, are poorly constrained by observations from Earth alone. ESA's Solar Orbiter no…
Magnetized winds of M-type stars and star-planet magnetic interactions: uncertainties and modeling strategy
Victor Réville, Jamie M. Jasinski, Marco Velli +6
M-type stars are the most common stars in the universe. They are ideal hosts for the search of exoplanets in the habitable zone (HZ), as their small size and low temperature make t…
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…
