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.
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]
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]
The orbital period of the system is 8.964 days, with the neutron star being eclipsed for about two days of each orbit by HD 77581. It has been given the variable star designation GP Velorum, and it varies from visual magnitude 6.76 to 6.99. [5] The spin period of the neutron star is about 283 seconds, and gives rise to strong X-ray pulsations.
Rays wheels are manufactured through two different processes: forging and casting. After each wheel is manufactured, the wheel goes through strenuous inspection before being packaged and shipped out. The following is a video showing each manufacturing process of a Rays Engineering wheel: Rays Engineering Manufacturing Process.
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 ...
It has the Bayer designation B Velorum, while HD 70930 is the star's identifier in the Henry Draper catalogue. With a combined apparent visual magnitude of 4.79, [ 2 ] it is visible to the naked eye as a faint point of light.
HR 3803 or N Velorum (N Vel) is a 3rd-magnitude star on the border between the southern constellations Carina and Vela. Based upon parallax measurements, it is approximately 223 light-years (68 parsecs) from Earth. It has a spectral classificafion of K5III, [3] indicating that it has evolved from the main sequence and is now a giant star.
