Abstract.
We present a grid of non-LTE metal-line-blanketed hydrostatic model atmospheres for various effective temperatures, surface gravities (luminosities), and metallicities. The metallicities range from an essentially metal-free, primordial composition to a solar composition. For each model, we calculate the exact radiation force and compare to gravity acceleration. We thus find for each metallicity, the maximum surface gravity as a function of effective temperature required for the radiation force to exceed gravity and thus to initiate a radiatively-driven wind.
