Scientific paper

In addition to photometric data of unprecedented quality, the Sloan Digital Sky Survey is also producing a massive spectroscopic database. The SDSS spectra have a wavelength coverage from 3800 to 9200 Ang, with a resolution of 1800. The recent Data Release 5 includes spectra for over 150,000 stars and nearly a million extragalactic objects. These stellar spectra have a great potential for both the studies of individual stars, and for using these stars as a probe of the Milky Way kinematics (radial velocity accuracy is 10-20 km/s). We will discuss determination of stellar parameters, such as effective temperature, gravity and metallicity from SDSS spectra, and will describe correlations between kinematics and other stellar properties, such as metallicity.
