WR 134 is a
variableWolf-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 five times the radius of the sun, but due to a temperature over 63,000
K it is 400,000 times as
luminous as the Sun.WR 134 was one of three stars in
Cygnus observed in 1867 to have unusual spectra consisting of intense
emission lines rather than the more normal continuum and
absorption lines. These were the first members of the class of stars that came to be called Wolf-Rayet stars (WR stars) after
Charles Wolf and
Georges Rayetwho discovered their unusual appearance.
[7] It is a member of the nitrogen sequence of WR stars, while the other two (
WR 135 and
WR 137) are both members of the carbon sequence that also have
OB companions. WR 134 has a spectrum with NIII and NIV emission between two and five times stronger than NV, leading to the assignment of a WN6 spectral type. The
spectrumalso shows strong HeII emission and weaker lines of HeIand CIV.
