Ejections of magnetic structures above a spherical wedge driven by a convective dynamo with differential rotation

Jörn Warnecke, Petri J. Käpylä, Maarit. J. Mantere +1

We combine a convectively driven dynamo in a spherical shell with a nearly isothermal density-stratified cooling layer that mimics some aspects of a stellar corona to study the eme…

Dynamo-driven plasmoid ejections above a spherical surface

Jörn Warnecke, Axel Brandenburg, Dhrubaditya Mitra

We extend earlier models of turbulent dynamos with an upper, nearly force-free exterior to spherical geometry, and study how flux emerges from lower layers to the upper ones withou…
