Session 32 - Stellar Astrophysics II.
Oral session, Monday, January 15
La Condesa, Hilton
Using the filter system for the Sloan Digital Sky Survey, I present photometry of stars at two galactic latitudes, 86.2\deg and 35.5\deg. The number densities and color distributions agree with standard galactic models. The bi-modal color distributions reflect halo and disk components. These distributions can be used to determine the mean color shift with an accuracy better than 0.1 mag. In color-color space, the stellar locus agrees with colors calculated for the main sequence, demonstrating usefulness of this system for selecting non-stellar objects based on photometry alone.
