Coronal influence on dynamos
Jörn Warnecke, Axel Brandenburg
We report on turbulent dynamo simulations in a spherical wedge with an outer coronal layer. We apply a two-layer model where the lower layer represents the convection zone and the…
Bipolar magnetic structures driven by stratified turbulence with a coronal envelope
Jörn Warnecke, Illa R. Losada, Axel Brandenburg +2
We report the spontaneous formation of bipolar magnetic structures in direct numerical simulations of stratified forced turbulence with an outer coronal envelope. The turbulence is…
Effects of enhanced stratification on equatorward dynamo wave propagation
Petri J. Käpylä, Maarit. J. Mantere, Elizabeth Cole +2
We present results from simulations of rotating magnetized turbulent convection in spherical wedge geometry representing parts of the latitudinal and longitudinal extents of a star…
Spoke-like differential rotation in a convective dynamo with a coronal envelope
Jörn Warnecke, Petri J. Käpylä, Maarit. J. Mantere +1
We report on the results of four convective dynamo simulations with an outer coronal layer. The magnetic field is self-consistently generated by the convective motions beneath the…
