The VIIth catalogue of galactic Wolf–Rayet stars
The VIIth catalogue of galactic Population I Wolf‐Rayet stars provides improved coordinates, spectral types and bv photometry of known WR stars and adds 71 new WR stars to the previous WR catalogue.Expand
Quantitative analysis of WC stars: constraints on neon abundances from ISO-SWS spectroscopy
Neon abundances are derived in four Galactic WC stars - gamma(2) Vel (WR 11, WC8+O7.5III), HD 156385 (WR 90, WC7), HD 192103 (WR 135, WC8) and WR 146 (WC5+O8) - using mid-infrared fine-structureExpand
Multi-frequency variations of the Wolf-Rayet system HD 193793. I : Infrared, X-ray and radio observations
Les observations RX, IR et radio du systeme Wolf-Rayet WR 140, WC 7 + O 4-5, realisees de 1979 a 1989 sont presentees. La photometrie IR, les courbes de lumiere, la periode, les elements orbitaux etExpand
The spectrum of the very massive binary system WR 20a (WN6ha + WN6ha): Fundamental parameters and wind interactions
We analyse the optical spectrum of the very massive binary system WR 20a (WN6ha + WN6ha). The most prominent emission lines, Hα and He  λ 4686, display strong phase-locked profile variability. FromExpand
Constraining the mass transfer in massive binaries through progenitor evolution models of Wolf-Rayet+O binaries
Since close WR+O binaries are the result of a strong interaction of both stars in massive close binary systems, they can be used to constrain the highly uncertain mass and angular momentum budgetExpand
A Very Large Array 3.6 Centimeter Continuum Survey of Galactic Wolf-Rayet Stars
We report the results of a survey of radio continuum emission of Galactic Wolf-Rayet (WR) stars north of delta=-46°. The observations were obtained at 8.46 GHz (3.6 cm) using the Very Large Array,Expand
A Westerbork Synthesis Radio Telescope 1400 and 350 MHz Continuum Survey of the Cygnus OB2 Association, in Search of Hot Massive Stars*
We present a radio continuum survey at 1400 and 350 MHz of a region of 2degrees x 2degrees centered on the Cygnus OB2 association (d = 1.7 kpc), using the Westerbork Synthesis Radio Telescope (WSRT)Expand
