WR 22, also known as V429 Carinae or HR 4188, is an eclipsing binary star system in the constellation Carina. The system contains a Wolf-Rayet (WR) star that is one of the most massive and most luminous stars known, and is also a bright X-ray source due to colliding winds with a less massive O class companion. Its eclipsing nature and apparent magnitude make it very useful for constraining the properties of luminous hydrogen-rich WR stars.

  • WR 22 – gwiazda podwójna znajdująca się w gwiazdozbiorze Kila w odległości około 5000 lat świetlnych od Słońca. Gwiazda ta jest gwiazdą Wolfa-Rayeta. WR 22 jest położona na obrzeżach mgławicy Carina, w której też powstała. WR 22 jest niezwykle gorącą i jasną gwiazdą odrzucającą w przestrzeń kosmiczną swoją atmosferę w tempie o wiele milionów razy większym niż Słońce. Jej masa wynosi co najmniej 70 mas Słońca. Pomimo dużej odległości od Słońca WR 22 w dobrych warunkach pogodowych jest widoczna gołym okiem. (pl)
