Radial structure and angular-momentum content of the stellar model with M_ini = 85 M_⊙ and ω = 0.15 as functions of enclosed mass M_r, together with the corresponding stellar and black-hole spin parameters. The adopted initial BH mass, M_BH, 0 = 3 M_⊙, is marked by the vertical dotted line. The black curve shows the radius R(M_r), the blue curve the cumulative angular momentum J(< M_r), the red dashed curve the stellar dimensionless spin a_★(M_r), and the red solid curve the BH spin $a_{\mathrm{BH}}^{(2)}(M_r)$ corresponding to the case with maximum feedback (no losses and ℳ_wind = 10), and the red dotted curve the BH spin $a_{\mathrm{BH}}^{(1)}(M_r)$ corresponding to the case with weaker feedback (with losses and ℳ_wind = 3). The vertical dashed blue line indicates the mass coordinate within which 50% of the star’s total angular momentum is enclosed.
