  1. Update: Ground-based observations Coralie Neiner

  2. Needs • Spectra in the RVS domain, R>11000 • SEDs for RP/BP • All hot and emission-line stars, in particular those for which modelling is still impossible or very difficult • To test identification and classification algorithms for CU6 and CU8

  3. Observations by the Liège group Gosset et al. • Catalogue of prototype stars for O, WN and WC stars • One star per subtype and luminosity • + a few OC, ON and Of stars • Northern and Southern hemispheres

  4. North: • time allocated at OHP/Aurélie • most of the targets already observed • reduction in progress… South: • service time allocated on NTT/EMMI • to be done…

  5. FEROS archive • contains O stars : list by Jean-Claude Bouret & Fabrice Martins • contains B and Be stars : list by Coralie Neiner, Anne-Marie Hubert et al. • maybe other interesting spectra in this database?

  6. GAIA-GBO observations Caroline Soubiran et al. • Observations of ESP stars • A few hundreds stars • At TBL/Narval (north) : proposal submitted • At ESO (south) : GAIA-ESO agreement in discussion… • Yves Frémat will provide the list of stars with the help of ESP members, including the SSUs ‘hot stars’ and ‘emission-line stars’ i.e. the GHOST
