Turbulent processes and mean-field dynamo
Axel Brandenburg, Detlef Elstner, Youhei Masada +1
Mean-field dynamo theory has important applications in solar physics and galactic magnetism. We discuss some of the many turbulence effects relevant to the generation of large-scal…
Various scenarios for the equatorward migration of sunspots
Detlef Elstner, Yori Fournier, Rainer Arlt
The profile of the differential rotation together with the sign of the alpha-effect determine the dynamo wave direction. In early models of the solar dynamo the dynamo wave often l…
Delayed Babcock-Leighton dynamos in the diffusion-dominated regime
Y. Fournier, R. Arlt, D. Elstner
Context. Solar dynamo models of Babcock-Leighton type typically assume the rise of magnetic flux tubes to be instantaneous. Solutions with high-magnetic-diffusivity have too short…
Investigating variation of latitudinal stellar spot rotation and its relation to the real stellar surface rotation
H. Korhonen, D. Elstner
In this work the latitude dependent stellar spot rotation is investigated based on dynamo models. The maps of the magnetic pressure at the surface from the dynamo calculations are…
Magnetic Structure of Rapidly Rotating FK Comae-Type Coronae
O. Cohen, J. J. Drake, V. L. Kashyap +3
We present a three-dimensional simulation of the corona of an FK Com-type rapidly rotating G giant using a magnetohydrodynamic model that was originally developed for the solar cor…
