Einstein and the Solar Eclipses - Why Albert Einstein joined the Astronomische Gesellschaft in Potsdam 1921
Günther Rüdiger
In 1911 Einstein suggested that photons which pass close to the Sun are deflected by its effective mass which would apparently shift the positions of stars by up to one arcsecond,…
Alpha tensor and dynamo excitation in turbulent fluids with anisotropic conductivity fluctuations
Oliver Gressel, Günther Rüdiger, Detlef Elstner
A mean-field theory of the electrodynamics of a turbulent fluid is formulated under the assumption that the molecular electric conductivity is correlated with the turbulent velocit…
On the toroidal-velocity anti-dynamo theorem under the presence of nonuniform electric conductivity
G. Rüdiger, M. Schultz
Laminar electrically conducting Couette flows with the hydrodynamically stable quasi-Keplerian rotation profile and non-uniform conductivity are probed for dynamo instability. In s…
Destabilization of super-rotating Taylor-Couette flows by current-free helical magnetic fields
G. Rüdiger, M. Schultz, R. Hollerbach
In an earlier paper we showed that the combination of azimuthal magnetic fields and super-rotation in Taylor-Couette flows of conducting fluids can be unstable against non-axisymme…
Cycle times of early M dwarf stars: mean field models versus observations
Manfred Küker, Günther Rüdiger, Katalin Oláh +1
Observations of early-type M stars suggest that there are two characteristic cycle times, one of order one year for fast rotators ( day) and another of order four…
Electrodynamics of turbulent fluids with fluctuating electric conductivity
G. Rüdiger, M. Küker, P. J. Käpylä
The influence of fluctuating conductivity on the coefficients known from the mean-field electrodynamics is considered. If the conductivity fluctuations are assumed as uncorrelated…
