First snapshot of a magnetosphere around a Herbig Ae/Be star
S. P. Järvinen, S. Hubrig, M. Küker +6
The Herbig Ae/Be star HD190073 is one of the very few magnetic Herbig Ae/Be stars for which close low-mass companions have been reported. Previously published magnetic field measur…

The turbulent pressure of magnetoconvection for slow and rapid rotation
M. Küker, G. Rüdiger
Motivated by recent simulations of sunspot formation, we extend the theory of the pressure difference between magnetized and non-magnetized gas by Dicke to include rotating turbule…

Mass loss and magnetospheres of massive stars
Manfred Küker
About ten percent of all OB stars show strong, large-scale surface magnetic fields. The interaction of the magnetic field and the wind is believed to be the cause for the X-ray emi…
