Additional viscosity that is required to reproduce the seismic rotation profiles of subgiants as a function of the ratio between the current stellar radius and the radius at the end of the MS (proxy for evolutionary stage). Filled squares and vertical arrows indicate the lower limits on ν_add obtained for KIC 5955122 (blue) and KIC 8524425 (red) with magnetic braking in the MS and crosses show the lower limits obtained without wind. Gray circles correspond to the evolved subgiants studied by Eggenberger et al. (2019b). The thick purple bar shows the efficiency of the AM transport during the main sequence for stars with masses between 1.1 and 1.2 M_⊙ obtained with open clusters (Spada & Lanzafame 2020).
