Effect of rotational mixing and metallicity on the hot star wind mass-loss rates

The metallicity dependence of the mass loss rate of hot stars is often described as scaling with the overall metallicity. The authors look into the impact of CNO processed material on the mass loss rate. Their calculations show that while it has small effect for solar metallicity stars, it can have important consequences for metal-poor stars.
