Gamma Velorum is a quadruple star system in the constellation Vela.This name is the Bayer designation for the star, which is Latinised from γ Velorum and abbreviated γ Vel.At a combined magnitude of +1.72, it is one of the brightest stars in the night sky, and contains by far the closest and brightest Wolf–Rayet star.
WR 12 (V378 Velorum) is a spectroscopic binary in the constellation Vela. It is an eclipsing binary consisting of a Wolf-Rayet star and a luminous companion of unknown spectral type. The primary is one of the most luminous stars known. The spectrum of WR 12 is dominated by the broad emission lines of the primary Wolf-Rayet star.
This is the list of notable stars in the constellation Vela, sorted by decreasing brightness.. This constellation's Bayer designations (Greek-letter star names) were given while it was still considered part of the constellation of Argo Navis.
A supergiant of spectral type K4Ib-II, it varies between magnitudes 2.14 and 2.3, [16] and lies 545 light-years distant. [17] It has around 11,000 times the luminosity, 9 to 12 times the mass and 207 times the diameter of the Sun. [18] AH Velorum is a Cepheid variable located less than a degree to the northeast of Gamma. [19]
It has the Bayer designation w Velorum, while HD 77258 is the identifier from the Henry Draper Catalogue. The system is visible to the naked eye as a faint point of light with a combined apparent visual magnitude of 4.45. [2] It is located at a distance of approximately 218 light years from the Sun based on parallax. [1]
The Gum Nebula (Gum 12) is an emission nebula that extends across 36° in the southern constellations Vela and Puppis. It lies approximately 450 parsecs from the Earth. [ 1 ] Hard to distinguish, it was widely believed to be the greatly expanded (and still expanding) remains of a supernova that took place about a million years ago.

WR 136, a WN6 star where the atmosphere shed during the red supergiant phase has been shocked by the hot, fast WR winds to form a visible bubble nebula. In 1867, using the 40 cm Foucault telescope at the Paris Observatory, astronomers Charles Wolf and Georges Rayet [1] discovered three stars in the constellation Cygnus (HD 191765, HD 192103 and HD 192641, now designated as WR 134, WR 135, and ...
