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] It is located at a distance of approximately 218 light years from the Sun based on parallax. [1]
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 ...
Vela X-1 is a pulsing, eclipsing high-mass X-ray binary (HMXB) system, associated with the Uhuru source 4U 0900-40 and the supergiant star HD 77581. The X-ray emission of the neutron star is caused by the capture and accretion of matter from the stellar wind of the supergiant companion.
In its quiescent state, V382 Velorum has a mean visual magnitude of 16.56. [6] It is classified as a fast nova with a smooth light curve. [7] [8] Like all novae, V382 Velorum is a binary system with two stars orbiting so close to each other that one star, the "donor" star, transfers matter to its companion star which is a white dwarf.
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 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.
