SDSS Spectroscopic Survey of Stars

Abstract

In addition to optical photometry of unprecedented quality, the Sloan Digital Sky Survey (SDSS) is also producing a massive spectroscopic database. We discuss determination of stellar parameters, such as effective temperature, gravity and metallicity from SDSS spectra, describe correlations between kinematics and metallicity, and study their variation as a function of the position in the Galaxy. We show that stellar parameter estimates by Beers et al. show a good correlation with the position of a star in the g - r vs. u - g color-color diagram, thereby demonstrating their robustness as well as a potential for photometric parameter estimation methods.
