These data will enable a sensitive dissection of its stellar populations, using a new set of reddening-free photometric indices we have constructed from broad-band filters across UV, optical, and near-IR wavelengths. These indices will provide accurate temperatures and metallicities for hundreds of thousands of individual bulge stars. Proper motions of these stars derived from multi-epoch observations will allow separation of pure bulge samples from foreground disk contamination. Our catalogs of proper motions and panchromatic photometry will support a wide range of bulge studies. Using these photometric and astrometric tools, we will reconstruct the detailed star-formation history as a function of position within the bulge, and thus differentiate between rapid- and extended-formation scenarios. We will also measure the dependence of the stellar mass function on metallicity, revealing how the characteristic mass of star formation varies with chemistry. Our sample of bulge stars with accurate metallicities will include 12 candidate hosts of extrasolar planets. Planet frequency is correlated with metallicity in the solar neighborhood; our measurements will extend this knowledge to a remote environment with a very distinct chemistry. Our proposal also includes observations of six well-studied globular and open star clusters; these observations will serve to calibrate our photometric indices, provide empirical population templates, and transform the theoretical isochrone libraries into the WFC3 filter system. Besides enabling our own program, these products will provide powerful new tools for a host of other stellar-population 12666( 3) - 06-Jul-2011 15:14:35 - [ 2] investigations with HST/WFC3. We will deliver all of the products from this Treasury Program to the community in a timely fashion. ------------------------------------------------------------------------------------ Observations Description ------------------------ This program is simply repeating the GO-11664/F814W exposures in 3 of the bulge fields (STANEK, BAADE, OGLE29), using the same orientation that executed previously, with at least a 2-year baseline between the exposures here and those in GO-11664. Unfortunately, Visit 13 (STANEK) is difficult to schedule at the same orientation that executed in Cycle 17, so it is using the 'SCHED 80" requirement and a shorter orbit.
