Hi,
I received the email but the Be catalog owner is really Coralie Neiner. She explained to us some time ago that there are not only emission line to make a star a Be Star. They look at temperature, class, IR dust etc... Let's see if Coralie replies.

To be confirmed but seems that V341 Sge is entering again an emission phase. Look at the short time between 2 spectra, less than 2 months.
See the historical data from BeSS. Valerie

Hi Welcome Elisabetta If you register to the yahoo group spectro-l then you will receive the BeSS monthly report activity :) And check the ArasBeAM portal to see what's beeing observed by the Be Stars amateur community around BeSS. http://arasbeam.free.fr/ I hope you can convert your spectra into Be...

Bonjour Emmanuel Il peut s'agir comme pour les etoiles Be, ou Herbig d'un disque circumstellaire ou tout autre matiere entourant l'etoile qui re-emet sous l'excitation du flux de l'étoile. Mais je ne connais pas ce type de variable. Tu es sur sinon que c'est une étoile double ? pas vu dans Simbad. V...

Hi For TESS BeSS stars of mag <8 here is a "book" of their past records in BeSS I used Vspec and its VO access to BeSS to generate the thumbnails and film composer feature to make a png. I had to design some code here to generate them from a list and not manually . As pdf file are not acce...

Hi Here the list of the TESS stars which are NOT in BeSS - just copy paste the list to one of your favorite excel tool alt_ID Tmag ST RA DEC BD+30_3853 7.007 B7V 300.244753 31.230478 MWC_314 7.678 sgB[e]? 290.39156 14.882506 Trumpler_37_1513 7.577 B5V 323.086269 59.572495 MWC_416 7.883 symB[e] 353.4...

Hi John

We are very happy to have you on board and proposing strategic and impactfull observations !

Hi There Exciting project to support TESS photometry observations ! I am relaying the infos posted by Oliiver Thizy on the Be star Spectra group on facebook. If you are already a BeSS observer registered, Olivier can grant you the access. Just go there and request to join. We use to put there the st...

Salut Franck Non je n'ai pas d'idée... Je pencherais pour des aberrations optiques dans le spectro qui peuvent changer avec les flexions mais je loin d'etre l'experte dans ce domaine... Quand tu dis que tu joues avec la hauteur de binning, tu veux dire que tu bin moins dans le rouge que dans le bleu...

Hi Here is a description of my process to acquire reference star to compute instrumental response with a Lhires and a grating of 2400tr/mm. I have seen some people taking reference star spectrum after each object, looking for a reference star at same elevation. This is the recommended procedure for ...
