WOLF-RAYET STARS SPECTROSCOPIC
SURVEY
Lastest update: 03/06/2013
The Wolf-Rayet stars are massive stars (more than 25 solar masses), in a advanced stage of evolution and ejecting at high speed a hot gas (winds of 2000 km/s typically). They have exceptional hot surface temperature, about 100.000 K. The spectrum presents strong emission widened lines. Wolf-Rayet stars have lost their atmospheres and have exposed their heavy cores. One finds there the signature of ions of helium, carbon, nitrogen and oxygen in the spectra.
There are 2 class Wolf-Rayet star: type WN where dominates the ions of helium and nitrogen and type WC where dominates the ions of carbon, oxygen and helium.
The Wolf-Rayet stars are very rare. One counts some hardly more than 150 in our galaxy. One will find below a list of bright Wolf-Rayet accessible since the northern hemisphere. The co-ordinates are into 2000.0 equinox.
