Mass-loss relations for Galactic metallicity. Mass-loss rates for H-free WN stars in the Galaxy as a function of luminosity. Black/grey stars indicate empirical mass-loss rates for Galactic WN stars with/without known distance from cluster membership (Hamann et al. 2006). The empirical mass-loss rates have been scaled down to those expected for a wind clumping factor of D = 10. The red curves indicate mass-loss rates obtained from our models with Z = 0.02 for ν/ νesc = 1.3 (top) and ν = 1800 km s-1 (bottom), the labels indicate stellar masses in M. The dotted/dashed lines indicate the empirical mass-loss prescriptions for H-free WN stars from Nugis & Lamers (2000) and Yoon (2017).
