2904 20160701171712.0 ASTROimport-1061 Sordo, R. 2009 New high resolution synthetic stellar libraries for the Gaia mission . 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 spectral ranges: 300/1100 nm at 0.1 nm resolution, and 840/890 nm at 0.001 nm resolution. These libraries span a wide atmospheric parameters range, from super-metal-rich to very metal-poor (-5.0 [Fe/H]+1.0), from cool to hot (T_{eff }=3000-50000 K) stars, including peculiar abundance variations. Thanks to their spectral resolution, spectral type coverage and number of models, they represent a substantial improvement over previous libraries used in population synthesis models and in atmospheric analysis.
