Gaia-HELIX is a new catalogue of 28,394 bona-fide Hα emitters identified in Gaia DR3 XP spectra, after removing 95% of initial candidates that were M-type star mimics.

abstract
We present a sample of 58 Be stars containing objects of spectral types O9 to B8.5 and luminosity classes III to V. We have obtained 3670 - 5070 Angstrom spectra of the sample which are used to derive spectral types and rotational velocities. We discuss the distribution of spectral types and rotational velocities obtained and conclude that there are no significant selection effects in our sample.
