Convection-driven spherical shell dynamos at varying Prandtl numbers
P. J. Käpylä, M. J. Käpylä, N. Olspert +2
(abidged) Context: Stellar convection zones are characterized by vigorous high-Reynolds number turbulence at low Prandtl numbers. Aims: We study the dynamo and differential rotatio…
Robustness of oscillatory dynamos in spherical wedges
E. Cole, A. Brandenburg, P. J. Käpylä +1
We study the connection between spherical wedge and full spherical shell geometries using simple mean-field dynamos. We solve the equations for a one-dimensional time-depende…
Turbulent transport coefficients in spherical wedge dynamo simulations of solar-like stars
Jörn Warnecke, Matthias Rheinhardt, S. Tuomisto +3
We investigate dynamo action in global compressible solar-like convective dynamos in the framework of mean-field theory. We simulate a solar-type star in a wedge-shaped spherical s…
