Quantitative Spectroscopy of O Stars at Low Metallicity: O Dwarfs in NGC 346
Quantitative Spectroscopy of O Stars at Low Metallicity: O Dwarfs in NGC 346
We present the results of a detailed UV and optical spectral analysis of the properties of 6 dwarf O-type stars in the SMC H II region NGC 346. Stellar parameters, chemical abundances, and wind parameters have been determined using NLTE line blanketed models calculated with the photospheric code, Tlusty, and …
