  • We discuss a solar dynamo model of Tayler–Spruit type whose Ω$\Omega $-effect is conventionally produced by a solar-like differential rotation but whose α$\alpha $-effect is assumed to be periodically modulated by planetary tidal forcing. This resonance-like effect has its rationale in the tendency of the current-driven Tayler instability to undergo intrinsic helicity oscillations which, in turn, can be synchronized by periodic tidal perturbations. Specifically, we focus on the 11.07-years… CONTINUE READING
