Magnetic and rotational quenching of the effect
Petri J. Käpylä
Context: Differential rotation in stars is driven by turbulent transport of angular momentum. Aims: To measure and parametrize the non-diffusive contribution to turbulent stress, k…
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…
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…
