Semiempirical versus Theoretical Stellar Population Models: A Comparison with Star Clusters

Semiempirical versus Theoretical Stellar Population Models: A Comparison with Star Clusters

Stellar population synthesis (SPS) models are a key tool for deriving the age, metallicity, radial velocity, and reddening of star clusters from their integrated spectra. Using a sample of 129 star clusters with high-quality spectra, we analyze the uncertainties associated with selecting an empirica...
