Internal structure (upper panel), angular momentum accretion rate (middle panel), and ratio v_surf/v_crit (lower panel) of the models described in Appendix B. Left-hand column shows the properties of the models started from a CV initial structure, while the right-hand column corresponds to the RC initial structure. On the top panel, the upper solid curve is the stellar radius, while convective and radiative zones are shown in dark and light grey, respectively. The dotted black curves are iso-mass at intervals of 1 M_⊙. In the middle panel, the coloured lines indicate the angular momentum effectively accreted by the models, and the black dotted curves show the value of j_accr corresponding to the indicated fraction of j_K. On the lower panel, the horizontal dotted line indicates the critical limit.
