Turbulent magnetic Prandtl numbers obtained with MHD Taylor-Couette flow experiments
M. Gellert, G. Ruediger
The stability problem of MHD Taylor-Couette flows with toroidal magnetic fields is considered in dependence on the magnetic Prandtl number. Only the most uniform (but not current-f…
Comment on "Helical MRI in magnetized Taylor-Couette flow"
G. Ruediger, R. Hollerbach
Liu et al. [Phys. Rev. E 74, 056302 (2006)] have presented a WKB analysis of the helical magnetorotational instability (HMRI), and claim that it does not exist for Keplerian rotati…
Sunspot models with bright rings
L. L. Kitchatinov, G. Ruediger
A theoretical sunspot model is provided including magnetic suppression of the diffusivities and also a strong stratification of density and temperature. Heat diffusion alone with g…
Destabilisation of hydrodynamically stable rotation laws by azimuthal magnetic fields
G. Ruediger, R. Hollerbach, M. Schultz +1
We consider the effect of toroidal magnetic fields on hydrodynamically stable Taylor-Couette differential rotation flows. For current-free magnetic fields a nonaxisymmetric m=1 mag…
Structure and stability of the magnetic solar tachocline
G. Ruediger, L. L. Kitchatinov
Rather weak fossil magnetic fields in the radiative core can produce the solar tachocline if the field is poloidal and almost horizontal in the tachocline region, i.e. if the field…
