[91.06] Halo streams and Milky Way Components from the Sloan Digital Sky Survey

H. J. Newberg (Rensselaer Polytechnic Institute), B. Yanny (Fermilab), Sloan Digital Sky Survey Collaboration

We present recent progress on identifying streams of stars in the halo from spatial data obtained for over five million stars in the Sloan Digital Sky Survey. We attempt to fit models for the thin disk, thick disk and halo stars to the data. We use color-magnitude diagrams to aid in the identification of separate stellar populations. We are able to see the turnoff, giant branch, horizontal branch, and blue straggler stars from the tidal stream of the Sagittarius dwarf galaxy. We measure the turnoff colors for other populations.
