Table 4.
Estimated line-of-sight velocity dispersion and dynamical masses from RSGs and B-type stars in the Hodge 301 and SL 639 clusters.
| σ1D (km s−1) | log(Mdyn/M⊙) | |
|---|---|---|
| Hodge 301 | ||
| RSG | 2.1  |
3.2 ± 1.0 |
| B-type | 5.8  |
4.1 ± 0.3 |
| All | 4.2  |
3.8 ± 0.3 |
| SL 639 | ||
| RSG | 1.4  |
<2.9 ± 0.9 |
| B-type | 3.1  |
<3.6 ± 1.0 |
| All | 1.9  |
<3.1 ± 0.8 |
Notes. Dynamical masses for SL 639 are upper limits as they adopt the same effective radius as Hodge 301 (reff = 1.68 pc).
