NW Ser outburst

Post by Olivier GARDE »

Last night, I took a spectrum of the Be star NW Ser and comparing it with the last one in the Bess database, we see that the emission line disappeared.
(graph not correct from heliocentric velocity)
Another spectra are welcome

La nuit dernière, j'ai réalisé un spectre de l'étoile Be NW Ser et en comparant le spectre avec le dernier dans la base Bess (qui a été fait également avec mon set up), on voit que la raie en emission a disparu..
(le graphe n'est pas corrigé de la vitesse héliocentrique)
Une confirmation serait souhaitable...

Hi Olivier, a quick shot some minutes ago with Lhires III 1200 (R~6000).

I think it confirm your observation, no emissions in the wings.

All the best,
Paolo
