Helioseismic Evidence That the Solar Dynamo Originates near the Tachocline
Krishnendu Mandal, Alexander G. Kosovichev
The exact location of the solar dynamo remains uncertain--whether it operates primarily in the near-surface shear layer, throughout the entire convection zone, or near the tachocli…
