New high resolution synthetic stellar libraries for the Gaia Mission
R. Sordo, A. Vallenari, J. C. Bouret +12
High resolution synthetic stellar libraries are of fundamental importance for the preparation of the Gaia Mission. We present new sets of spectral stellar libraries covering two sp…
The Carina dSph galaxy: where is the edge?
G. Bono, M. Monelli, A. R. Walker +13
Recent cosmological N-body simulations suggest that current empirical estimates of tidal radii in dSphs might be underestimated by at least one order of magnitude. To constrain the…
Spectroscopic Survey of the Galaxy with Gaia II. The expected science yield from the Radial Velocity Spectrometer
M. I. Wilkinson, A. Vallenari, C. Turon +21
The Gaia mission is designed as a Galaxy explorer, and will measure simultaneously, in a survey mode, the five or six phase space parameters of all stars brighter than 20th magnitu…
Spectroscopic survey of the Galaxy with Gaia I. Design and performance of the Radial Velocity Spectrometer
D. Katz, U. Munari, M. Cropper +22
The definition and optimisation studies for the Gaia satellite spectrograph, the Radial Velocity Spectrometer (RVS), converged in late 2002 with the adoption of the instrument base…
The angular size of dwarf stars and subgiants - Surface brightness relations calibrated by interferometry
P. Kervella, F. Thevenin, E. Di Folco +1
The availability of a number of new interferometric measurements of Main Sequence and subgiant stars makes it possible to calibrate the surface brightness relations of these stars…
Modeling of Alpha Cen and Procyon using VLTI observations
P. Kervella, F. Thevenin, P. Morel +4
We present a novel approach to model the nearby stars Alpha Cen A & B and Procyon A using asteroseismic and interferometric constraints. Using the VINCI instrument installed at the…
