The striking broad emission line spectroscopic appearance of Wolf-Rayet (WR) stars has
long defied analysis, owing to the extreme physical conditions within their line-and …

The VIIth catalogue of galactic PopulationI Wolf–Rayet stars provides improved coordinates,
spectral types and bv photometry of known WR stars and adds 71 new WR stars to the …

Context. The mass loss from Wolf-Rayet (WR) stars is of fundamental importance for the final
fate of massive stars and their chemical yields. Its Z-dependence is discussed in relation to …

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 …

Almost all known Galactic single WN stars have been analyzed applying non-LTE models
for spherically expanding atmospheres. While in a previous study we performed" coarse" …

Wolf-Rayet (WR) stars are luminous, massive blue stars thought to be the immediate
precursors to some supernovae. The existence of dust shells around such stars has been …

Massive Star Populations in Nearby Galaxies ADS Classic is now deprecated. It will be
completely retired in October 2019. This page will automatically redirect to the new ADS interface …

We present high-resolution spectroscopic monitoring of the line-profile variations (LPVs) in
the He II λ 5411 emission line of four Wolf-Rayet (WR) stars of the WN sequence (HD 96548 …

Abstract New Technology Telescope (NTT)/Son of Isaac (SOFI) imaging and spectroscopy of
the Wolf–Rayet population in the massive cluster Westerlund 1 are presented. Narrow-band …

We construct revised near-infrared absolute magnitude calibrations for 126 Galactic Wolf–
Rayet (WR) stars at known distances, based in part upon recent large-scale spectroscopic …
