Diamagnetic pumping near the base of a stellar convection zone
L. L. Kitchatinov, G. Rüdiger
The property of inhomogeneous turbulence in conducting fluids to expel large-scale magnetic fields in the direction of decreasing turbulence intensity is shown as important for the…
Stability of toroidal magnetic fields in the solar tachocline and beneath
L. L. Kitchatinov, G. Rüdiger
Stability of toroidal magnetic field in a stellar radiation zone is considered for the cases of uniform and differential rotation. In the rigidly rotating radiative core shortly be…
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…
Stability of Toroidal Magnetic Fields in Rotating Stellar Radiation Zones
L. L. Kitchatinov, G. Ruediger
The questions of how strong magnetic fields can be stored in rotating stellar radiative zones without being subjected to pinch-type instabilities and how much radial mixing is prod…
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…
Do mean-field dynamos in nonrotating turbulent shear-flows exist?
G. Ruediger, L. L. Kitchatinov
A plane-shear flow in a fluid with forced turbulence is considered. If the fluid is electrically-conducting then a mean electromotive force (EMF) results even without basic rotatio…
