9 stars looks new Be, to be confirm in High resolution

[Thierry Lemoult]

Hello

These past week i observe a few hundred of B star thanks to an automated script. I do a first visual scan of the raw image and find évident emission in Ha for 9 stars:

BD+60 133
BD+28 4177
BD+57 2581
BD+59 2675
BD+60 2523
BD+63 1964 ??? look strange...
BD+64 106
HD 237126
HR 8107

All these stars need rapid confirmation in High resolution.
Regards
Thierry

Thierry, a significant hall well done. I think BD+64 106 has been seen before as per my email but the others do not show as Be in the Catalogue of Stellar Spectral Classifications (Skiff, 2009-2014).

I doubt I will have any left to find if you proceed at this rate!

Impressionnant travail Thierry !
Peux-tu détailler ta méthode d'enregistrement des spectres en automatique ?
Quel script et logiciel utilises-tu et surtout comment fais-tu pour arriver à positionner automatiquement une étoile sur la fente du spectro ?
Merci des infos et encore bravo !

Many stars can look as Be. From my personnal data base and a long and patient bibliography research (at a time there was no Internet!), some example, nether entered in the "official" Be data base:

HD4881 (Simbad type: B9.5V):


HD5839 (Simbad type B9 (?))


HD191639 (Simbad B1V, noted Be in Simbad... but can be also a beta Cep star, ... )


...

I hope you have better luck. The role of Coralie Neiner is important for analysis and confirmation.
But already, an essential first step is accomplished: the detection of suspected cases (and compilation of
a public list for reseach and more observations). Perfect.

(PS: it's clear the aspect of BD+69 1969 spectrum seem very different of a A or B type star).

Hi François

A good idea !

Can you lock the threads here and add a link to their new location so that people do not add to them here ? (Thierry Garrel I think has already added a profile)
Also I suggest adding this thread
http://www.spectro-aras.com/forum/viewt ... ?f=6&t=929
so we can investigate these new published ABE stars before they become officially Be stars in BeSS

Cheers
Robin
