[62.12] Open and Globular Cluster Distances for Stellar, Galactic, and Extragalactic Astrophysics

G. Worthey (St. Ambrose University)

SIM will be able to obtain <2% parallax distances approximately to the Galactic center. This non-key project targets selected clusters (both open and globular) within the Milky Way in order to address issues of (1) extragalactic distance scale, (2) cluster ages, (3) stellar evolutionary isochrone calibration and the integrated light models used in extragalactic and cosmological stellar population studies, (4) the chemical evolution of the galaxy and galaxies in general, and (5) valuable partial information on horizontal branch and asymptotic giant branch evolution.
