Dynamo action in M-dwarfs
S. B. F. Dorch, B. V. Gudiksen, H. -G. Ludwig
Magnetic activity in M-dwarfs present enigmatic questions: On the one hand they have higher field strengths and larger filling factors than the magnetic field on the Sun, on the ot…
On the Saturation of Astrophysical Dynamos: Numerical Experiments with the No-cosines flow
S. B. F. Dorch, V. D. Archontis
In the context of astrophysical dynamos we illustrate that the no-cosines flow, with zero mean helicity, can drive fast dynamo action and study the dynamo's mode of operation durin…
Dynamo action in late-type giants
S. B. F. Dorch
Recent numerical MHD simulations suggest that magnetic activity may occur in late-type giants. A entire red supergiant with stellar parameters equal to Betelgeuse was modelled in 3…
Magnetic activity in late-type giant stars: Numerical MHD simulations of non-linear dynamo action in Betelgeuse
S. B. F. Dorch
Evidence is presented from numerical magneto-hydrodynamical simulations for the existence of magnetic activity in late-type giant stars. A red supergiant with stellar parameters si…
