Specific angular momentum for the rotating 85   M_⊙ (left) and 60   M_⊙ (right) models as a function of the Lagrangian mass coordinate normalised to the actual total mass of the star. The continuous (black) curve corresponds to the ZAMS, the short-dashed (green) curve to the beginning of the core He-burning phase, the long-dashed (red) curve to the beginning of the C-burning phase, and the medium-dashed (purple) curve to the end of the C-burning phase. The dot-short-dashed (blue) curve indicates the minimum specific angular momentum for a stable circular orbit around a Schwarzschild black-hole and the dot-long-dashed (blue) indicates the minimum specific angular momentum for a stable circular orbit around a maximally rotating Kerr black-hole. The grey area cuts the lines at the point corresponding to the mass coordinate equal to the mass of the remnant indicated in Table 4. The surface equatorial velocities are indicated for each stage.
