Bonjour à tous, il semble que le H-alpha dans cette étoile commence à aller en emission.

Wow, that detection is right at the edge of a low-res spectrograph! Yes, a narrow emission component of h-alpha line is present now. I observed the star with Lhires III 1200 just half an hour after you. A long exposure because the trasparency decreased (light clouds showed up in the sky).
