THE LARGE SKY AREA MULTI-OBJECT FIBER SPECTROSCOPIC TELESCOPE (LAMOST)

摘要

Ⅰ. THE SCIENTIFIC BACKGROUND AND SIGNIFICANCE Abundant physical information about remote celestial bodies is contained in their optical spectra. The optical spectra of enormous amount of celestial bodies are critical in astronomical research of wide field of view and large samples that concerns various frontiers in astronomy and astrophysics. Up to now, however, among the tens of billions of all kinds of celestial bodies recorded by imaging surveys, only a very little part (about one ten thousandth)
