a and b: specific angular momentum (solid lines) and hydrogen mass fraction (dotted lines) profiles for two SMC models of masses 5 and 15 M_⊙ and initial equatorial velocities of 370 and 470 km s⁻¹ respectively. These are the same models plotted in panels b and d of Fig. 2 and both models have initial critical velocity fractions of around 0.6. Profiles are plotted for models where central helium mass fraction is 0.45 (black), and 0.91 (orange). c: for each model in panels a and b the fractional difference in specific angular momentum is plotted between the two times. The blue line represents the 5 M_⊙ model, the orange the 15 M_⊙ model. The dotted red line gives a reference for no angular momentum transport. The X-axis in all plots indicates the fractional mass co-ordinate.
