J'ai pas trop trouvé de littérature sur ce type de spectre d'étoile, notamment sur l'identification des divers raies.
Here's two spectra of Wolf Rayet stars (WR 140 and WR 133) taken with a C14 and a LISA spectrograh (seven exposures of 300 seconds for each target)
I haven't found any document on this type of stars, and especially on the identification of the various lines present in the spectrum.
