The prototype, located in the constellation Vela, 2.8° north-northeast of Gamma Velorum, is the brightest of its class, with a magnitude range of 6.4 to 7.1. AI Velorum stars were formerly known as a dwarf Cepheids.
Wolf-Rayet stars (or WR stars) are very massive stars, with a surface temperature between 25,000 and 50,000 kelvins, luminosity from 100,000 to 1 million times the Sun's and a mass from 10 to 50 times the Sun's. The star Gamma Velorum (in the ...
About 200 of these stars are known in the Milky Way; most of these are very far from us. The W-R star closest to us is the double star gamma Velorum (in the constellation Vela). Wolf-Rayet stars were discovered in 1867 by C. J. Wolf and G.
