It is located 1.65 billion light years away from Earth and is a Seyfert galaxy and an ultraluminous infrared galaxy. [1] IRAS 01003-2238 is also classified as a Wolf-Rayet galaxy , making the object one of the most distant known.
WR 22, also known as V429 Carinae or HR 4188, is an eclipsing binary star system in the constellation Carina.The system contains a Wolf-Rayet (WR) star that is one of the most massive and most luminous stars known, and is also a bright X-ray source due to colliding winds with a less massive O class companion.
NGC 6822-WR 12 is a WN-type Wolf-Rayet star located in the galaxy NGC 6822, about 1.54 million light years away [4] in the constellation of Sagittarius.NGC 6822-WR 12 was the first Wolf-Rayet star to be discovered in the galaxy, [5] and is one of only four known in the galaxy.
NGC 6888 (Crescent Nebula) NGC 2359 (Thor's Helmet Nebula) M1-67 (Luminous Blue Variable Nebula) NGC 3199 (Nebula around WR 18) These nebulae exhibit intricate structures revealed in visible light as well as infrared, X-ray, and other wavelengths, providing insight into the powerful stellar winds and evolutionary processes around Wolf-Rayet stars.
NGC 2359 (also known as Thor's Helmet) is an emission nebula [3] in the constellation Canis Major. The nebula is approximately 3,670 parsecs (11.96 thousand light years) away and 30 light-years in size. The central star is the Wolf-Rayet star WR7, an extremely hot star thought to be in a brief pre-supernova stage of evolution.
WR 25 (HD 93162) is a binary star system in the turbulent star-forming region of the Carina Nebula, about 6,800 light-years from Earth. It contains a Wolf-Rayet star and a hot luminous companion and is a member of the Trumpler 16 cluster. The name comes from the Catalogue of Galactic Wolf–Rayet Stars.
M1-67 is an ejecta nebula that surrounds the Wolf–Rayet star WR 124, which is about 6.4 kpc from Earth [2] in the constellation of Sagitta.It contains dust which is caught up in WR 124's solar wind and which absorbs much of the star's light.
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 ...
