Laboratory experiments on dynamo action and magnetically triggered flow instabilities
F. Stefani, A. Gailitis, G. Gerbeth +4
Magnetic fields of planets, stars and galaxies are generated by self-excitation in moving electrically conducting fluids. Once produced, magnetic fields can play an active role in…
Magnetic field dynamos and magnetically triggered flow instabilities
Frank Stefani, Thomas Albrecht, Rainer Arlt +13
The project A2 of the LIMTECH Alliance aimed at a better understanding of those magnetohydrodynamic instabilities that are relevant for the generation and the action of cosmic magn…
The effective magnetic Prandtl number in magnetized and differentially rotating stellar radiation zones
G. Ruediger, M. Schultz, L. L. Kitchatinov
With application to inner stellar radiative zones, a linear theory is used to analyze the instability of a dipole-parity toroidal background field, in the presence of density strat…
Linear stability analysis of the Hall magnetorotational instability in a spherical domain
T. Kondic, G. Ruediger, R. Arlt
We investigate the stability of the Hall-MHD system and determine its importance for neutron stars at their birth, when they still consist of differentially rotating plasma permeat…
The cross helicity at the solar surface by simulations and observations
G. Ruediger, M. Kueker, R. S. Schnerr
The quasilinear mean-field theory for driven MHD turbulence leads to the result that the observed cross helicity <u \cdot b> may directly yield the magnetic eddy diffusivity η_{T}…
Helicity and dynamo action in magnetized stellar radiation zones
G. Ruediger, L. L. Kitchatinov, D. Elstner
Helicity and αeffect driven by the nonaxisymmetric Tayler instability of toroidal magnetic fields in stellar radiation zones are computed. In the linear approximation a purely toro…
