Explaining the 12C/13C ratio in the Galactic halo: The contribution from shell mergers in primordial massive stars

Open Access

Fig. 2

¹²C/¹³C ratio in the stellar models of Limongi & Chieffi (2018), for stars that contribute via both wind and explosion (first row) or only wind (second row), for the three initial rotation velocities 0 (left), 150 (centre) and 300 (right) km s⁻¹. Where dots are missing the models do not predict enrichment of ¹²C or ¹³C, or both.
