Evgeny P. Velikhov (1935-2024)
Günther Rüdiger
The master student at Lomonosov University in Moscow E.P. Velikhov formulated 1959 the theory of magnetorotational instability, which dominates current astrophysics. A meteoric car…
Tayler instability and dynamo action of cylindric magnetic rings
Günther Rüdiger, Manfred Schultz
The Tayler instability of an azimuthal magnetic field with one or two ``rings'' along the radius is studied for an axially unbounded Taylor-Couette flow. The rotation law of the co…
Angular momentum transport by magnetoconvection and the magnetic modulation of the solar differential rotation
Günther Rüdiger, Manfred Küker
In order to explain the variance of the solar rotation law during the activity minima and maxima, the angular momentum transport by rotating magnetoconvection is simulated in a con…
Large-scale dynamo action of magnetized Taylor-Couette flows
G. Rüdiger, M. Schultz
A conducting Taylor-Couette flow with quasi-Keplerian rotation law containing a toroidal magnetic field serves as a mean-field dynamo model of the Tayler-Spruit-type. The flows are…
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…
Differential rotation and meridional flow of Arcturus
Manfred Küker, Günther Rüdiger
The spectroscopic variability of Arcturus hints at cyclic activity cycle and differential rotation. This could provide a test of current theoretical models of solar and stellar dyn…
