Dynamo cycles in global convection simulations of solar-like stars
Jörn Warnecke
Several solar-like stars exhibit cyclic magnetic activity similar to the Sun as found in photospheric and chromospheric emission. We want to understand the physical mechanism invol…
Transition from axi- to nonaxisymmetric dynamo modes in spherical convection models of solar-like stars
Mariangela Viviani, Jörn Warnecke, Maarit J. Käpylä +5
We seek to understand the transition from nearly axisymmetric configurations at solar rotation rates to nonaxisymmetric configurations for rapid rotation using 3D numerical simulat…
A new look at sunspot formation using theory and observations
Illa R. Losada, Jörn Warnecke, Kolja Glogowski +4
Sunspots are of basic interest in the study of the Sun. Their relevance ranges from them being an activity indicator of magnetic fields to being the place where coronal mass ejecti…
Extended subadiabatic layer in simulations of overshooting convection
Petri J. Käpylä, Matthias Rheinhardt, Axel Brandenburg +5
We present numerical simulations of hydrodynamic overshooting convection in local Cartesian domains. We find that a substantial fraction of the lower part of the convection zone (C…
