Yields for the main isotopes of the CNO cycle for the different values of α_ov and log(D_env/cm² s⁻¹) (dots connected by lines). The horizontal lines indicate the yields of 20 M_⊙ models (dashed, dashed-dotted, and dotted lines) with different rotational velocities (0, 150, and 300 km/s, from Brinkman (2022)). The isotopes are ¹²C, ¹³C, ¹⁴N, ¹⁵N, ¹⁶O, and in the last panel ¹⁷O (solid lines) and ¹⁸O (dash-dotted lines). In this panel, the grey horizontal lines are for ¹⁷O and the black horizontal lines are for ¹⁸O. The lower panels show the ratio between the yield of the reference models (log(D_env/cm² s⁻¹) = 0) and the models with the other values for log(D_env/cm² s⁻¹).
