The Discordance of Mass‐Loss Estimates for Galactic O‐Type Stars
The Discordance of Mass‐Loss Estimates for Galactic O‐Type Stars
We have determined accurate values of the product of the mass-loss rate and the ion fraction of P^{4+}, Mdot q(P^{4+}), for a sample of 40 Galactic O-type stars by fitting stellar-wind profiles to observations of the P V resonance doublet obtained with FUSE, ORFEUS/BEFS, and Copernicus. When P^{4+} is the …
