Description:
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. This
census of galactic WR stars reaches 227 stars, comprising 127 WN
stars, 87 WC stars, 10 WN/WC stars and 3 WO stars. This includes 15
WNL and 11 WCL stars within 30 pc of the Galactic Center. We compile
and discuss WR spectral classification, variability, periodicity,
binarity, terminal wind velocities, correlation with open clusters and
OB associations, and correlation with H I bubbles, H II regions and
ring nebulae. Intrinsic colours and absolute visual magnitudes per
subtype are re-assessed for a re-determination of optical photometric
distances and galactic distribution of WR stars. In the solar
neighbourhood we find projected on the galactic plane a surface
density of 3.3 WR stars per kpc2, with a WC/WN number ratio of 1.5,
and a WR binary frequency (including probable binaries) of 39%. The
galactocentric distance (RWR) distribution per subtype shows RWR
increasing with decreasing WR subtype, both for the WN and WC
subtypes. This RWR distribution allows for the possibility of
WNE->WCE and WNL->WCL subtype evolution.
The successive catalogues of galactic WR stars are:
