Chemical abundance ratios of galactic globular clusters from modelling integrated light spectroscopy
galactic globular clusters light spectroscopy
2011/1/10
We use our new, flux-calibrated stellar population model of absorption-line indices to derive ages, metallicities, and various element abundance ratios from integrated light spectroscopy of galactic g...
