Table 8.
Estimates of the excess number (E40) of nitrogen-rich targets with enhancements of greater than 0.3 dex that are not due to rotational mixing in single stars.
| Sample | NGC 346 | VFTS | FSMS |
|---|---|---|---|
| Galaxy | SMC | LMC | LMC |
| E40 | 11.3 | 5.0 | 5.1 |
| N | 211 | 220 | 103 |
| N40 | 24 | 21 | 12 |
| PT(%) | 5.4 | 2.3 | 4.9 |
| P40(%) | 47 | 24 | 42 |
| PT(%) | ≤9.6 | ≤5.5 | – |
| P40(%) | ≤85 | ≤57 | – |
Notes. Also listed are the total number of apparently single B-type stars (N) and the inferred number (N40) of these targets that have ve ≤ 40 km s−1. These have been used to estimate the corresponding percentages compared with the total number of apparently single B-type stars (PT) and with the number of targets that have ve ≤ 40 km s−1 (P40).
