Journal ArticleDOI
Synchronized Helicity Oscillations: A Link Between Planetary Tides and the Solar Cycle?
TL;DR: In this article, the authors examined the helicity oscillations that were recently found in simulations of the current-driven, kink-type Tayler instability, which is characterized by an azimuthal dependence.
Journal ArticleDOI
Synchronized helicity oscillations: a link between planetary tides and the solar cycle?
TL;DR: In this paper, it was shown that the 11.07 years tidal oscillation induced by the Venus-Earth-Jupiter system may lead to a 1:1 resonant excitation of the oscillation of the alpha effect.
Journal ArticleDOI
DRESDYN -- a new facility for MHD experiments with liquid sodium
Frank Stefani,Sven Eckert,Gunter Gerbeth,André Giesecke,Th. Gundrum,C. Steglich,Tom Weier,B. Wustmann +7 more
TL;DR: The DREsden Sodium facility for DYNamo and thermohydraulic studies (DRESDYN) as mentioned in this paper is intended as a platform both for large scale experiments related to geo- and astrophysics as well as for experiments of liquid metal batteries and liquid metal fast reactors.
Journal ArticleDOI
A model of a tidally synchronized solar dynamo
TL;DR: In this article, a solar dynamo model of the Tayler-Spruit type whose Omega effect is conventionally produced by a solar-like differential rotation but whose alpha effect is periodically modulated by planetary tidal forcing is discussed.
Journal ArticleDOI
Role of soft-iron impellers on the mode selection in the von kármán-sodium dynamo experiment.
TL;DR: Numerical simulations of a VKS-like dynamo with a localized permeability distribution that resembles the shape of the flow driving impellers show that the presence of soft-iron material essentially determines the dynamo process in the VKS experiment.
