Abstract We propose a three-year program to provide both observational and theoretical mid- ultraviolet (2300A -- 3100A) spectral templates for interpreting the age and metallicity of globular clusters and elliptical galaxies from spectra of their integrated light. The mid-UV is the region most directly influenced by stellar age, and is observed directly in optical and infrared studies of high-redshift quiescent systems. The reliability of age and metallicity determinations remains questionable until non-solar metallicities and abundance ratios are considered, and stars spanning the color-magnitude diagram are included, as we propose here. With archival HST STIS spectra we have improved the list of mid-UV atomic line parameters, then calculated spectra from first principles which match observed spectra of standard stars up to one- fourth solar metallicity. We will extend both observations and calculations to stars of solar metallicity and beyond, and to those in short-lived stages hotter than the main-sequence turnoff, stars not currently well-represented in empirical libraries. The necessary line-list improvements will come from new high-resolution mid-UV spectra of nine field stars. A key application of the results of this program will be to the old systems now being discovered as `Extremely Red Objects' at high redshifts. Reliable age-dating of these places constraints on the epoch when large structures first formed in the universe. ------------------------------------------------------------------------------------ 9455( 6) - 07/24/03 09:25 - [ 2] Observations Description ------------------------ This is the first year of a three-year Treasury program to obtain mid-UV spectra of stars and M31 globular clusters, in order to develop tools and methods for deriving the age and metallicity of old stellar systems from spectra of their integrated light. In Cycle 11, mid-UV high-resolution echelle spectra will be obtained for standard stars, to extend to solar metallicity the calibration of the mid-UV line list (see Peterson, Dorman, & Rood 2001, ApJ, 559, 372). The proprietary period is waived for all data.
