Characterization of white-light enhancements under umbral conditions in one-dimensional simulations of solar flares
Sascha Ornig, Mats Carlsson
Solar flares with signatures in the optical continuum (white light, WL) pose a challenge to the standard flare model and to solar flare simulations. In particular, simulations are…
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…
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…
