Does Betelgeuse have a magnetic field?
S. B. F. Dorch, B. Freytag
Recent numerical simulations by Freytag et al. of the outer convection envelope of the cool super-giant Betelgeuse, have shown that the fluctuations in the star's apparent luminosi…

Small-scale magnetic fields on late-type M-dwarfs
S. B. F. Dorch, H. -G. Ludwig
We performed kinematic studies of the evolution of small-scale magnetic fields in the surface laters of M-dwarfs. We solved the induction equation for a prescribed velocity field,…

Numerical Simulations of Kinematic Dynamo Action
Vasilis Archontis, Bertil Dorch, Aake Nordlund
Numerical simulations of kinematic dynamo action in steady and 3-d ABC flows are presented with special focus on growth rates and multiple periods of the prescribed velocity field.…
