Structure of rotating models in advanced phases of the evolution for initial masses 120 M_⊙ (top left; end of C-burning phase), 20 M_⊙ (top right; end of C-burning phase), 7 M_⊙ (bottom left; early AGB phase), and 2.5 M_⊙ (bottom right; early AGB phase). We show three panels for each initial mass. Top panel: chemical structure as a function of the Lagrangian mass coordinate M(r), with the mass fractions of H (black solid line), He (black dashed), ¹²C (red long dashed), ¹⁴N (green solid), ¹⁶O (blue dot-dashed), ²⁰Ne (magenta dot-long dashed), ²²Ne (magenta short-long dashed), and ²⁴Mg (black short-long dashed). Middle panel: radius as a function of the Lagrangian mass coordinate. We also indicate the location of the maximum energy production of the He- and H-burning shells. Lower panel: variation of the angular velocity as a function of the Lagrangian mass coordinate, with the labels indicating the ratio of the angular velocity to the critical velocity at selected positions.
