The GHOST in CU8
GHOST website: http://www.ster.kuleuven.be/~coralie/gaiahot.html
CU = Coordination Unit For CU8: manager=CBJ, deputy=Frederic Thevenin, scientific coordinator=CBJ, technical coordinator=Michel Nonon
DU = Development Unit = a group of people contributing to a CU or a sub-part of a CU (with a DU coordinator) GHOST = Gaia Hot Stars Team = a DU
(G)WP = (Gaia) Work Package = a group of tasks to be performed in a CU (with a WP manager and sub-WP managers)
SSU = Specific Stars Unit
The CUs of GAIA
CU8 Astrophysical parameters
Work Beakdown Structure
GWP-C-8110Coordination and management
GWP-C-8120Definition of system architecture
models for hot stars and emission line stars (contributors: Y.Frémat, R. Blomme, C. Martayan, J. Zorec, J.-C. Bouret, F. Martins,…) Y. Frémat this afternoon
make sure the interstellar extinction is treated properly in emission line stars…
provide typical criteria for hot stars and emission line stars?
provide typical photometric criteria for hot stars and emission line stars?
provide typical spectral criteria for hot stars and emission line stars?
provide spectral criteria for hot stars and emission line stars?
GWP-S-8350Object Clustering Analysis (OCA) (Sarro)
provide algorithms for unsupervised classification for hot stars and emission line stars?
Would the algorithm developed in Leuven be useful here?
help to determine the G-band magnitude and luminosity, which are crucial for the age and mass determination, for hot stars and emission line stars

Study, develop and test algorithmswhich provideextended parameter estimates for the considered stars.
What needs to be done
(before launch in 2011)
- Help with study, development and test of algorithms to provide luminosity, mass and age estimates (GWP-S-8360) (Frémat et al.?) 2006-2010
