2 The GAIA Mission 6D Phase Space (V<20) and Astrophysical Parameters (V<16) for 10 9 stars Science: Galaxy Dynamics, Distances, Extinction, Stellar Astrophysics, Rare Objects and Events, Exoplanets, Solar System Objects, Variability, Supernovae, GRB, Rapid Alerts, Fundamental Physics, Galaxies, Extragalactic Objects, QSO … _______________________________________________ Elena Pancino - INAF Visiting Committee (Dec 2007)

3 GAIA Instruments _______________________________________________ Elena Pancino - INAF Visiting Committee (Dec 2007) Imager: Astrometry G-Band Imaging HR Spectrometer: CaT (847–874 nm) LR Spectrophotometers: BP & RP (330–680; 640–1050 nm)

4 The DPAC _______________________________________________ Elena Pancino - INAF Visiting Committee (Dec 2007) AO Response Accepted Dec 2006

5 Italian Effort on Gaia _______________________________________________ Elena Pancino - INAF Visiting Committee (Dec 2007) P.I.: M. Lattanzi (TO) INAF: INAF Staff (Salaries) and Small Expenses ASI: Missions, Contracts, Hardware (until launch 2012) 1.6 M ( ) - Total Manpower 30 FTE (2007) Involvement in all CUs, but mainly: CU3 (Core, Astrometry): Torino CU4 (Object Analysis): Torino CU5 (Photometry): Bologna, Roma, Teramo CU7 (Variability): Bologna, Napoli, Catania CU8 (Astrophysical Parameters): Padova Italy is the 2nd contributor after France

6 OABO Involvement in Gaia _______________________________________________ Elena Pancino - INAF Visiting Committee (Dec 2007) Absolute Flux Calibration of all Gaia Photometry (CU5): BP/RP Spectrophotometry ( nm) G-Band Imaging from Astrometric Field Design of Algorithm and Java Classes Ground Based Observations of SPSS Total Manpower in Bologna (4.5/6.5/7.0) MM/Yr Variability GBObs, RR Lyrae and Cepheids (CU7): Supplementary Ground Based and Space Observations RR Lyrae and Cepheids Classification and Parameters Total Manpower in Bologna (0.3/1.5/ 3.5) MM/Yr

7 Absolute Calibration (CU5) DU13 - Ground Based Observations _______________________________________________ Elena Pancino - INAF Visiting Committee (Dec 2007) Work Package: GWP-513-M Manager: E.
