Description

Etoile de Wolf Rayet de type WN5 w + B . Système double. Peut être triple.
Le spectre cumule les raies des deux étoiles . La période du système est de 1763 jours.
Les raies de l'azote ionisé 3 fois (N IV) et de l'helium ionisé (He II) sont intenses, et clairement visibles à basse résolution.
Mon spectre est ici probablement pollué par un bruit de fond "parasite" . A refaire !
