A Wolf-Rayet nebula is a type of nebula created from stellar winds expelled by Wolf-Rayet stars. Wolf-Rayet stars are very hot, highly luminous , and rapidly evolving massive stars that are fusing helium or heavier elements in their cores.
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 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 .
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 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]
WR 31a, commonly referred to as Hen 3-519, is a Wolf–Rayet (WR) star in the southern constellation of Carina that is surrounded by an expanding Wolf–Rayet nebula.It is not a classical old stripped-envelope WR star, but a young massive star which still has some hydrogen left in its atmosphere.
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.
