Synopsis of the structure and the induced transport of angular momentum in stars with an external and an internal convection zone. Convection and radiation zones are depicted in grey and orange. The short dashed blue lines represent the equatorial trapping due to the Coriolis acceleration and the Lorentz force and the purple long-dashed lines represent the vertical magnetic trapping. Finally, the vertical fluxes of energy and of angular momentum are represented by the thin dark grey arrow and the large green one.
