Synthetic spectroscopic indices for identifying multiple stellar populations in globular clusters

We present an investigation of synthetic spectroscopic indices that can plausibly help in identifying the presence of multiple stellar populations in globular clusters. The study is based on a new grid of stellar model atmospheres and high-resolution (R = 500 000) synthetic spectra, that consider chemical partitions that have been singled out in Galactic globular clusters. The data base is compose...
