Stellar yields of nitrogen for the 9 (blue) and 20 M_⊙ (orange) models at different metallicities (0 ≤ Z ≤ 0.020). The circles connected by the solid curve correspond to models with an initial rotation of υ_ini = 0.4 υ_crit and the diamonds ones with υ_ini = 0.7 υ_crit. The moderately rotating models are from Murphy et al. (2021a, Z = 0), Sibony et al. (in prep., Z = 10⁻⁵), Groh et al. (2019, Z = 0.0004), Georgy et al. (2013a, Z = 0.002), Ekström et al. (2012, Z = 0.014), Eggenberger et al. (2021, Z = 0.006), and Yusof et al. (2022, Z = 0.020).
