Table 4.
Initial values of CNO abundances adopted in the evolutionary grids referred to in this work, and corresponding solar values from Asplund et al. (2009).
| Solar | Brott et al. (2011) | Ekström et al. (2012) | |
|---|---|---|---|
| ϵC | 8.43 | 8.13 | 8.39 |
| ϵN | 7.83 | 7.64 | 7.78 |
| ϵO | 8.69 | 8.55 | 8.66 |
Notes. The abundances from Brott et al. (2011) have been tailored to represent the CNO abundances from the young open cluster NGC 6611 (see text).
