Mass-loss estimates for YHGs and RSGs.

Source Spectral type ATCA (M yr−1)
W12a F1Ia+ 1.66 ± 0.02 × 10−5
W4a F3Ia+ 2.59 ± 0.02 × 10−5
W32 F5Ia+ 3.01 ± 0.50 × 10−6
W265 F5Ia+ 1.10 ± 0.03 × 10−5
W237 M3Ia 2.00 ± 0.02 × 10−6
W75 M4Ia 7.27 ± 0.48 × 10−7
W20 M5Ia 3.28 ± 0.03 × 10−6

Notes. Fluxes were used from core components of the emission attributed to the YHGs and RSGs, as given by the FULLCONCAT dataset. These mass-loss rates are calculated for objects where an approximation of a thermally emitting stellar wind is considered valid, using the Wright and Barlow equation (Wright & Barlow 1975).
