Mean period of core rotation as a function of the asteroseismic stellar radius, in log–log scale. Crosses correspond to RGB stars, triangles to clump stars, and squares to secondary clump stars. The colour code gives the mass estimated from the asteroseismic global parameters. The dotted line indicates a rotation period varying as R². The dashed (dot-dashed, triple-dotted-dashed) line indicates the fit of RGB (clump, secondary clump) core rotation period. The rectangles in the right side indicate the typical error boxes, as a function of the rotation period. From Mosser et al. [160].
