Using a significantly revised non-LTE radiative transfer code that allows for the effects of line blanketing by He, C, O, Si, and Fe, we have performed a detailed analysis of the Galactic Wolf-Rayet (W-R) star HD 165763 (WR 111, WC5). Standard W-R models consistently overestimate the strength of the electron scattering wings, especially on strong lines, so we have considered models where the wind is both homogeneous and clumped. The deduced stellar parameters for HD 165763 are as follows: The… Expand
The Galactic WC stars Stellar parameters from spectral analyses indicate a new evolutionary sequence
[Abridged] [...] AIMS: We aim to establish the stellar parameters and mass-loss rates of the Galactic WC stars. These data provide the empirical basis of studies of (i) the role of WC stars in theExpand
No breakdown of the radiatively driven wind theory in low-metallicity environments
We present a spectroscopic analysis of HST/COS observations of three massive stars in the low metallicity dwarf galaxies IC 1613 and WLM. These stars, were previously observed with VLT/X-shooter byExpand
Modelling the colliding-winds spectra of the 19-d WR + OB binary in the massive triple system θ Muscae
High signal-to-noise ratio, moderate-resolution spectra, providing full phase coverage of the 19-d WC6 + OB binary θ Mus (WR 48, HD 113904), have been obtained and show dramatic variations of the CExpand
Realistic ionizing fluxes for young stellar populations from 0.05 to 2 Z
We present a new grid of ionizing fluxes for O and Wolf‐Rayet (W‐R) stars for use with evolutionary synthesis codes and single-star H II region analyses. A total of 230 expanding, non-LTE,Expand
Stellar and wind properties of LMC WC4 stars A metallicity dependence for Wolf-Rayet mass-loss rates ?
We use ultraviolet space-based (FUSE, HST) and optical/IR ground-based (2.3 m MSSSO, NTT) spectroscopy to determine the physical parameters of six WC4-type Wolf-Rayet stars in the Large MagellanicExpand
Wolf-Rayet stars in the Small Magellanic Cloud: I. Analysis of the single WN stars
Wolf-Rayet (WR) stars have a severe impact on their environments owing to their strong ionizing radiation fields and powerful stellar winds. Since these winds are considered to be driven by radiationExpand
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
Tailored Analyses of the WN 8 Stars WR 40 and WR 16
We present the results of tailored spectral analyses of two WN 8 Wolf-Rayet stars: WR 40 (HD 96548) and WR 16 (HD 86161). These analyses were carried out utilizing line-blanketed non-LTE modelExpand
The Wolf-Rayet stars in the Large Magellanic Cloud - A comprehensive analysis of the WN class
Context. Massive stars, although being important building blocks of galaxies, are still not fully understood. This especially holds true for Wolf-Rayet (WR) stars with their strong mass loss, whoseExpand
The Geometry of HD 165763: A Polarization Study of a WC Star

WC Stars: Hot Stars with Cold Winds
The atmospheric structure of WC stars is studied. Detailed models reveal that the ionization of the envelope systematically decreases farther out into the wind. C(4+) and He(2+) dominate close to theExpand

Numerical values of the radiation pressure on spectral lines are presented for the envelopes of stars with type O--G, and with any luminosity, metallicity, or velocity structure. The lineExpand
Diagnostics of Wolf-Rayet Atmospheres
Classic modeling techniques cannot be used to analyze Wolf-Rayet (W-R) spectra. At a minimum one must consider spherical geometry, non-LTE, and the transfer of radiation in an expanding atmosphere. AExpand

Infrared (1.0-3.4 μm) recombination lines of six WC stars are analysed following the method of Hummer, Barlow & Storey (1982, IAU Symp. No. 99). Improved spectral resolution and increased wavelengthExpand
Line profiles variations from atmospheric eclipses: Constraints on the wind structure in Wolf-Rayet stars
Binary systems in which one of the components has a stellar wind may present a phenomenon known as 'wind' or 'atmospheric eclipse', in which that wind occults the luminous disk of the companion. TheExpand
