Title: Spectra of star clusters in the LMC as an age indicator.
Abstract:
We propose to obtain spectrophotometry for a sample of 40 LMC star
clusters of different ages to provide a means to accurately calibrate
their integrated spectral properties in terms of age and metallicity.
Our sample of 40 clusters have previously established ages and
metallicities from modern, stellar, color-magnitude diagrams and the
analysis of individual red giants spectra. This calibration effort is
essential for improving studies of unresolved, extragalactic stellar
populations. Integrated spectroscopy of stellar clusters is
particularly important to obtain ages and metallicities of star clusters
in distant galaxies, to determine their star formation and chemical
enrichment history.
