3D MHD modelling of a chromosphere above the sun's convective zone
Abstract
We report on the extension of the ASH code to include an atmospheric stable layer (i.e not convective). This layer is meant to model the sun's chromosphere within the anelastic approximation limits while coping with the wide range of densities, time and spatial scales between r = 0.7 Rsolar and r = 1.03 Rsolar. Convective overshoot into the stable atmospheric layer is observed in a region ~ 0.01 Rsolar thick, exciting waves which propagate upwards into the atmosphere.
