Structure in the motions of the fastest halo stars
P. ReFiorentin, A. Helmi, M. G. Lattanzi +1
We have analyzed the catalog of 2106 non-kinematically selected metal poor stars in the solar neighborhood published by Beers et al. (2000), with the goal of quantifying the amount…
The GAIA Astrometric Survey of the Solar Neighborhood and its Contribution to the Target Database for DARWIN/TPF
A. Sozzetti, S. Casertano, M. G. Lattanzi +1
We evaluate the potential of the ESA Cornerstone Mission GAIA in helping populate the database of nearby stars ( pc) for subsequent target selection for DARWIN/TPF. The GAI…
Galaxy structure and kinematics towards the NGP
A. Spagna, C. Cacciari, R. Drimmel +3
We present a proper motion survey over about 200 square degrees towards the NGP, based on the material used for the construction of the GSC-II, that we are using to study the verti…
Faint and peculiar objects in GAIA: results from GSC-II
D. Carollo, A. Spagna, M. G. Lattanzi +3
The one billion objects in the GSC-II make up a formidable data set for the hunt of peculiar and rare targets such as late type stars, white dwarfs, carbon dwarfs, asteroids, varia…
Hipparcos Positioning of Geminga : How and Why
P. A. Caraveo, M. G. Lattanzi, G. Massone +4
Accuracy in the absolute position in the sky is one of the limiting factors for pulsar timing, and timing parameters have a direct impact on the understanding of the physics of Iso…
Distances and Absolute Ages of Galactic Globular Clusters from Hipparcos Parallaxes of Local Subdwarfs
R. G. Gratton, F. Fusi Pecci, E. Carretta +3
High precision trigonometric parallaxes from the HIPPARCOS satellite and accurate metal abundances ([Fe/H], [O/Fe], and [alpha/Fe]) from high resolution spectroscopy for about 30 l…
