Left panel, top: time evolution of the total mass of the models. The magnetic models computed for this work are plotted in black (rotating model) and red (non-rotating model). Models from Yusof et al. (2013) are shown for comparison: non-magnetic rotating model at solar metallicity (thin dashed black line) and SMC metallicity (thin dashed blue line). Key evolutionary phases are indicated: beginning of the WR phase (star), end of the MS (circle), and end of central He burning (triangle). Left panel, bottom: time evolution of the escaping wind fraction f_B (see Eq. (1)) for the magnetic rotating (black) and non-rotating (red) models. Centre panel: HRD tracks for the same models as in left panel. The meaning of the colours and symbols is the same. Iso-radii are indicated in light grey (1, 10, and 100 R_⊙ from left to right). Right panel: time evolution of the surface velocity of our models. We use the same colour scheme as for the top left panel.
