The empirical metallicity dependence of the mass-loss rate of O- and early B-type stars
We present a comprehensive study of the observational dependence of the mass-loss rate in stationary stellar winds of hot massive stars on the metal content of their atmospheres. The metal content ofExpand
Atmospheric NLTE-models for the spectroscopic analysis of blue stars with winds. II. Line-blanketed models
Received; accepted Abstract. We present new or improved methods for calculating NLTE, line-blanketed model atmospheres for hot stars with winds (spectral types A to O), with particular emphasis on aExpand
The VLT-FLAMES survey of massive stars: wind properties and evolution of hot massive stars in the Large Magellanic Cloud
We have studied the optical spectra of a sample of 28 O- and early B-type stars in the Large Magellanic Cloud, 22 of which are associated with the young star forming region N11. Our observationsExpand
Spectral analysis of early-type stars using a genetic algorithm based fitting method
We present the first automated fitting method for the quantita tive spectroscopy of O- and early B-type stars with stellar winds. The method combines the non-LTE stellar atmosphere codefastwind fromExpand
The VLT-FLAMES survey of massive stars: mass loss and rotation of early-type stars in the SMC
We have studied the optical spectra of a sample of 31 O- and early B-type stars in the Small Magellanic Cloud, 21 of which are associated with the young massive cluster NGC 346. Stellar parametersExpand
Quantitative H and K band spectroscopy of Galactic OB-stars at medium resolution
In this paper we have analyzed 25 Galactic O and early B-stars by means of H  and K  band spectroscopy, with the primary goal to investigate to what extent a lone near-IR spectroscopy is able toExpand
The VLT-FLAMES Survey of Massive Stars
The VLT-FLAMES Survey of Massive Stars was an ESO Large Programme to understand rotational mixing and stellar mass loss in different metallicity environments, in order to better constrain massiveExpand
VLT/UVES spectroscopy of the O supergiant companion to 4U 1907+09(7)
High-resolution optical spectra of the high-mass X-ray binary 4U 1907+09 covering the wavelength range 4680−10 400 A indicate that the X-ray pulsar's massive companion is an O8/O9 supergiant with aExpand
The VLT-FLAMES Survey of Massive Stars: Observations in the Galactic Clusters NGC 3293, NGC 4755 and NGC 6611 ⋆
We introduce a new survey of massive stars in the Galaxy and the Magellanic Clouds using the Fibre Large Array Multi-Element Spectrograph (FLAMES) instrument at the Very Large Telescope (VLT). HereExpand
Modeling the near-infrared lines of O-type stars
We use a grid of 30 line-blanketed unified stellar photosphere and wind models for O-type stars; computed with the code  in order to evaluate its potential in the near-infrared spectral domain.Expand
