Tidal triggers and the predictability of solar activity
F. Stefani, G. M. Horstmann, G. Mamatsashvili +1
Magneto-Rossby waves in the solar tachocline are currently considered to be one of the main determinants of solar activity. In particular, they can give rise to the quasi-biennial…
One-winged butterflies: mode selection for azimuthal magnetorotational instability by thermal convection
A. Mishra, G. Mamatsashvili, M. Seilmayer +1
The effects of thermal convection on turbulence in accretion discs, and particularly its interplay with the magnetorotational instability (MRI), are of significant astrophysical in…
Schwabe, Gleissberg, Suess-de Vries: Towards a consistent model of planetary synchronization of solar cycles
F. Stefani, A. Giesecke, M. Seilmayer +2
Aiming at a consistent planetary synchronization model of both short-term and long-term solar cycles, we start with an analysis of Schove's historical data of cycle maxima. Their d…
The Tayler instability at low magnetic Prandtl numbers: Chiral symmetry breaking and synchronizable helicity oscillations
F. Stefani, V. Galindo, A. Giesecke +2
The current-driven, kink-type Tayler instability (TI) is a key ingredient of the Tayler-Spruit dynamo model for the generation of stellar magnetic fields, but is also discussed as…
Subcritical excitation of the current-driven Tayler instability by super-rotation
G. Rüdiger, M. Schultz, M. Gellert +1
It is known that in a hydrodynamic Taylor-Couette system uniform rotation or a rotation law with positive shear ('super-rotation') are linearly stable. It is also known that a cond…
