a) Azimuthally and temporally averaged rotation frequency. Yellow denotes the rotation rate of the interior, red is the higher rotation rate and blue the lower rotation rate. b) Radial profile of rotation frequency at different latitudes. c) Meridional circulation in the radiation zone (left) and in the convection zone (right), evaluated from the poloidal mass flux averaged over time and longitude. Solid contours denote counterclockwise circulation, dashed contours clockwise circulation.
