WR 140 is a visually moderately bright Wolf–Rayet star placed within the spectroscopic binary star, SBC9 1232, [7] whose primary star is an evolved spectral class O4–5 star. [7] It is located in the constellation of Cygnus , lying in the sky at the centre of the triangle formed by Deneb , γ Cygni and δ Cygni .
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.
WR 134 is a variable Wolf-Rayet star located around 6,000 light years away from Earth in the constellation of Cygnus, surrounded by a faint bubble nebula blown by the intense radiation and fast wind from the star.
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 ...
WR 135 is a variable Wolf-Rayet star located around 6,000 light years away from Earth in the constellation of Cygnus, surrounded by a faint bubble nebula blown by the intense radiation and fast wind from the star. It is just over four times the radius of the sun, but due to a temperature of 63,000 K it is 250,000 times as luminous as the sun.
WR 124 is a Wolf–Rayet star in the constellation of Sagitta surrounded by a ring nebula of expelled material known as M1-67. [9] It is one of the fastest runaway stars in the Milky Way with a radial velocity around 200 km/s. It was discovered by Paul W. Merrill in 1938, identified as a high-velocity Wolf–Rayet star. [10]
The nebula is bubble-like and surrounds a Wolf–Rayet star named EZ Canis Majoris. This star is in the brief, pre- supernova phase of its stellar evolution . The nebula is about 4,530 light-years (1,389 parsecs ) away from Earth , [ 3 ] but some sources indicate that both the star and the nebula are up to 5,870 ly (1,800 pc) away.
VFTS 682 is a Wolf–Rayet star in the Large Magellanic Cloud.It is located over 29 parsecs (95 ly) north-east of the massive cluster R136 in the Tarantula Nebula. [5] It is 138 times the mass of the Sun and 3.2 million times more luminous, which makes it one of the most massive and most luminous stars known.
