Coronal ejections from convective spherical shell dynamos [PDF]
Jörn Warnecke, Petri J. Käpylä, Maarit. J. Mantere, Axel BrandenburgWe 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.View original: http://arxiv.org/abs/1111.1763
