Editing Wolf–Rayet star (section)

=== Modern WR catalogues ===
The sixth Catalogue of Galactic Wolf–Rayet stars was the first to actually bear that name, as well as to describe the previous five catalogues by that name. It also introduced the WR numbers widely used ever since for galactic WR stars. These are again a numerical sequence from WR 1 to WR 158 in order of right ascension.<ref name="VIth">{{cite journal|doi=10.1007/BF00173260|title=The Sixth Catalogue of galactic Wolf–Rayet stars, their past and present|journal=Space Science Reviews|volume=28|issue=3|pages=227–306|date=1981|last1=Van Der Hucht|first1=Karel A.|author-link1=Karel van der Hucht|last2=Conti|first2=Peter S.|last3=Lundström|first3=Ingemar|last4=Stenholm|first4=Björn|bibcode=1981SSRv...28..227V|s2cid=121477300}}</ref> 

Compiled in 2001, the seventh catalogue and its annex used the same numbering scheme and inserted new stars into the sequence using lower case letter suffixes, for example [[WR 102ka]] for one of the numerous WR stars discovered in the galactic centre.<ref name="hucht" /><ref name="annex">{{cite journal|doi=10.1051/0004-6361:20065819|title=New Galactic Wolf–Rayet stars, and candidates|journal=Astronomy and Astrophysics|volume=458|issue=2|pages=453–459|date=2006|last1=Van Der Hucht|first1=K.

In 2011, an online Galactic Wolf Rayet Catalogue was set up, hosted by the [[University of Sheffield]].  As of February 2025, it includes 709 stars.<ref name=":1">{{Cite web |title=Wolf-Rayet Star Catalogue |url=https://pacrowther.staff.shef.ac.uk/WRcat/ |access-date=2025-01-17 |website=pacrowther.staff.shef.ac.uk}}</ref>
