Title:
The Transition From Small-N to Large-N Astronomy: Galaxy Formation and Evolution, One Star at a Time

Lecturer:
Prof. Timothy C. Beers
(Dept. of Physics & Astronomy, Michigan State University, On sabbatial at NAOJ（国立天文台）, Tokyo)

日時・場所:
平成１３年３月２１日(水) 16:00-
物理専攻 大学院講義室 (2-2-11)にて
( March 21 (Wed.), 2001, 16:00 @ Grad. School Lecture Room, Div. of Phys. (2-2-11) )

要旨：　I present a summary of several ongoing projects concerned with the kinematics and dynamics of metal-poor stars in the Milky Way galaxy, and with the evolution of elemental abundances as studied by high-resolution spectra of extremely metal-deficient stars. A snapshot of the rapidly growing database of information is used to provide clues to the formation of the various known structural components of the Milky Way (inner halo, outer halo, metal-weak thick disk, thick disk, bulge, thin disk). We also present new results from the first Large-N, high signal-to-noise, high-resolution survey of stars in the Galaxy with [Fe/H] < -2.5, and suggest how one might accelerate the identification of the most interesting and important metal-poor stars, such as those with large r-process overabundances that can be used for cosmo-chronometry.
