Radial profiles of rotational velocity are shown at representative times for Delta0 model for different mass groups. The line of sight is the same as described in Sect. 2. The rotational velocity is normalised by the central velocity dispersion (inner 1% of stars) of all stars (FG + SG). Time and radius normalisations are the same as described in Fig. 2. Mass groups are split into low- (0.1-0.3 M_⊙), intermediate-(0.3-0.7 M_⊙), and high- (0.7-1 M_⊙) mass bins.
