Abstract
The recent VIIth Catalogue of Galactic Wolf-Rayet Stars lists 227 Population I WR stars, comprising 127 WN, 87 WC, 10 WN/WC and 3 WO stars. Additional discoveries bring the census to 234 WR stars. A re-determination of the optical photometric distances and the galactic distribution of WR stars shows in the solar neighbourhood a projected surface density of 2.7 WR stars per kpc2, a N WC/N WN number ratio of 1.3, and a WR binary frequency of 40%. The galactocentric distance (R WR) distribution per subtype shows R WN and R WC decreasing with WN and WC subtypes.
