Quantifying the effect of turbulent magnetic diffusion on the growth rate of the magneto-rotational instability
M. S. Väisälä, A. Brandenburg, Dhrubaditya Mitra +2
In astrophysics, turbulent diffusion is often used in place of microphysical diffusion to avoid resolving the small scales. However, we expect this approach to break down when time…
Azimuthal dynamo wave in spherical shell convection
Elizabeth Cole, Petri J. Käpylä, Maarit J. Mantere +1
We report the finding of an azimuthal dynamo wave of a low-order (m=1) mode in direct numerical simulations (DNS) of turbulent convection in spherical shells. Such waves are predic…
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…
