| Abstract: |
To better understand Wolf-Rayet stars as progenitors of gamma-ray bursts, an understanding of the effect metallicity has on Wolf-Rayet mass loss is needed. Using simple analytic models, we study the dM/dt − Z relation of a WN star and compare the results to similar models. We find that dM/dt roughly follows a power law in Z with index 0.88 from −2.5 ≤ logZ/ZSolar ≤ −1 and appears to flatten by logZ/ZSolar ∼ −0.5. |
