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.
The other Wolf-Rayet stars that can be seen with the naked eye (although it can only be seen with the naked eye under excellent viewing conditions) are γ 2 Velorum (WR 11), θ Muscae (WR 48), WR 22, WR 24 and HD 151932 (WR 78). HD 152408 is about 24 times as massive as the Sun. Like most extremely massive stars, it is losing mass via its ...
AH Velorum is a Cepheid variable located less than a degree to the northeast of Gamma. [19] A yellow-white supergiant of spectral type F7Ib-II, it pulsates between magnitudes 5.5 and 5.89 over 4.2 days. [20] Also lying close to Gamma, [21] V Velorum is a Cepheid of spectral type F6-F9II ranging from magnitude 7.2 to 7.9 over 4.4 days. [22]
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 ]

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.
A new review reports that nine people taking semaglutide and tirzepatide — the active ingredient in GLP-1 medications — experienced vision issues, including three potentially blinding eye ...
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 ...
