Breaking gyrochronology through the collapse of coronal winds
Michaël Lévesque, Paul Charbonneau
Gyrochronology, a method for dating aged field stars ( a few Gyr) based on their rotation rate, has recently been shown to fail for many stars older than the sun. The expl…
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…
Avalanching together: A model for sympathetic flaring
Louis-Simon Guité, Paul Charbonneau, Antoine Strugarek
Avalanche models running in a self-organized critical regime have proven powerful in reproducing the power-law distributions and scale invariance that characterize the statistical…
Flaring together: A preferred angular separation between sympathetic flares on the Sun
Louis-Simon Guité, Antoine Strugarek, Paul Charbonneau
Sympathetic solar flares are eruptions that occur nearby in space and time, driven by an apparent interaction between the active regions in which they are triggered. Their statisti…
Hot Spot Offset Variability from Magnetohydrodynamical Thermoresistive Instability in Hot Jupiters
Raphaël Hardy, Paul Charbonneau, Andrew Cumming
Hot Jupiter atmospheres are possibly subject to a thermoresistive instability. Such an instability may develop as the ohmic heating increases the electrical conductivity in a posit…
Energy Definition and Minimization in Avalanche Models for Solar Flares
Henri Lamarre, Paul Charbonneau, Antoine Strugarek
Self-organised critical avalanche models are a class of cellular automata that, despite their simplicity, can be applied to the modeling of solar (and stellar) flares and generate…
On the sensitivity of magnetic cycles in global simulations of solar-like stars
A. Strugarek, P. Beaudoin, P. Charbonneau +1
The periods of magnetic activity cycles in the Sun and solar-type stars do not exhibit a simple or even single trend with respect to rotation rate or luminosity. Dynamo models can…
Stellar Structure Modeling using a Parallel Genetic Algorithm for Objective Global Optimization
T. S. Metcalfe, P. Charbonneau
Genetic algorithms are a class of heuristic search techniques that apply basic evolutionary operators in a computational setting. We have designed a fully parallel and distributed…
