Good result despite the low luminosity

Very fast nova.
Expansion velocity 4900-5100 km/s measured on H alpha and H beta.

Impressive! Very high velocity.
Thus nova event produced by a high mass white dwarf, small mass of the accreted envelop and large part of the envelop ejected.
Congratulations.

Bonjour Pierre-Bernard,

Une démarche trés intéressante.
Peux-tu nous montrer un example ou deux?

Bienvenue sur le Forum

Bienvenue Olivier.
A voir les spectres de bet et eps Ori que tu présentes, les débuts sont plutôt bien maîtrisés! Excellent.

The new season of observations after the solar conjunction is begining. Since the detection of the end of the high state (2015-2023), T CrB evolves in the same way as before the high state with orbital variations of the photometry and spectroscopic appearence.
