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.
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 ]
WY Velorum, also known as HD 81137, is a binary system between a variable red supergiant (RSG) and a blue giant companion in the constellation of Vela. It is located approximately 1,900 parsecs (6,200 light-years) distant.
An extreme oxygen-rich red hypergiant that has experienced two dimming periods in the 20th century where the star became dimmer by up to 2.5 magnitudes. [16] Potentially the largest known star. [14] There is a possilbility that this size might be a bit overestimated (on the order of 1 sigma). Hence, the quoted radius might be just an upper ...
It shows photometric variations with multiple periods around 4.6 days and line-profile variations with a period of 2.318 days. The radial velocity of this star is constant. [ 4 ] It has 10 [ 7 ] times the Sun's radius and shines with 3,082 [ 5 ] times the Sun's luminosity from its photosphere at an effective temperature of 15,000 K .
HD 74180 is a single [12] star in the constellation Vela.It is a yellow-white F-type supergiant with a mean apparent magnitude of +3.81 and a spectral classification F8Ib. . Estimates of its distance to Earth vary between 3,200 and 8,300 lig
The star has 2.17 [5] times the mass of the Sun and 2.11 [5] times the Sun's radius. It is radiating 23 [ 5 ] times the Sun's luminosity from its photosphere at an effective temperature of 9,451 K. [ 6 ] An infrared excess has been detected from HD 88955, which analysis suggests is a (3.6 ± 3.0) × 10 −7 M 🜨 debris disc with a mean ...
