    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 ...

    en.wikipedia.org/wiki/WR_104

    The primary star is a WolfRayet star (abbreviated as WR), which has a B0.5 main sequence star in close orbit and another more distant fainter companion. The WR star is surrounded by a distinctive spiral WolfRayet nebula, often referred to as a pinwheel nebula. The rotational axis of the binary system, and likely of the two closest stars ...

    WR 124 is a WolfRayet 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 WolfRayet star. [10]
