Abstract:
We are using the McDonald 2.7m and ESO 1.52m telescopes
to obtain spectra of
nearby stars at high-resolution, high S/N, and with complete optical
coverage. The sample includes all stars in the Hipparcos catalog
brighter than MV = 6.5 (~ K2 V) within a 12770 pc3
sphere centered at the Sun.
The survey is 78 % complete. The database will be publicly released in
approximately 1 year. We plan to: 1) Provide homogeneous radial velocities
with the accuracy required to exploiting in full the accurate proper motions
and parallaxes determined by Hipparcos
(0.1 < Sigma(v) < 1.0 km s-1);
2) Provide homogeneous chemical abundances for a large (> 30) number of
elements with an accuracy of 0.04 dex; 3) Determine the fundamental stellar
parameters for the sample using an array of different methods. We
discuss potential applications.
