Coronal ejections from convective spherical shell dynamos
arXiv:1111.1763 · doi:10.1017/S1743921312004772
Abstract
We present a three-dimensional model of rotating convection combined with a simplified corona in spherical coordinates. The motions in the convection zone generate a large-scale magnetic field that gets sporadically ejected into the outer layers above. Our model corona is approximately isothermal, but it includes density stratification due to gravity.
