Mass loss parameters of WNE stars: dependence on metallicity.

NUGIS T., ANNUK K. and HIRV A.

Abstract (from CDS):

Mass-loss rates and luminosities of single WNE (WN2-WN5) stars in the LMC and SMC were determined by using empirically scaled formulae. The comparison with the Galactic WNE stars allows one to conclude that the mass-loss rates of WNE stars depend on the initial metallicity Z to about the first power, but this dependence may be much weaker if the flux enhancement due to clumping is weaker at smaller initial metallicities. The terminal velocities of WNE-star winds are somewhat smaller at lower initial metallicity, but this dependence is quite weak.
