Galaxy Formation: One Star at a Time. New Information from the Kinematics of Field Stars in the Galaxy
Timothy C. Beers, Masashi Chiba
Abstract
We present a review of recent studies of the formation and evolution of the Milky Way galaxy, in particular based on large samples of non-kinematically selected stars with available proper motions. The Milky Way is argued to be a reasonable template for the formation of large spiral galaxies, the only one in which complete kinematical and abundance information can be readily obtained. Ongoing and future projects to obtain proper motions and spectral information for much larger samples of stars that will sharpen our perspective are discussed.
