| Abstract: |
We present a quantitative spectroscopic analysis of six O-type stars in the low-metallicity galaxies IC 1613, WLM, and NGC 3109. The obtained wind strengths for the objects in WLM and NGC 3109 are surprisingly high, and do not agree with theoretical predictions. The objects in IC 1613 also tend toward a higher than expected mass-loss rate, but remain consistent with predictions from
radiation-driven wind theory within their error bars. |
