Are planets setting the sun's pace?

(Helmholtz-Zentrum Dresden-Rossendorf) The sun's activity is determined by the sun's magnetic field. Two combined effects are responsible for the latter: the omega and the alpha effect. Exactly where and how the alpha effect originates is currently unknown. Researchers at the Helmholtz-Zentrum Dresden-Rossendorf are putting forward a new theory for this in the journal Solar Physics.
