Old stellar populations. V.

Listed in IVOA Registry (Virtual Observatory)

Twenty-one optical absorption features, 11 of which have been previously defined, are automatically measured in a sample of 460 stars.

Description

Following Gorgas et al., the indices are summarized in fitting functions that give index strengths as functions of stellar temperature, gravity, and [Fe/H]. This project was carried out with the purpose of predicting index strengths in the integrated light of stellar populations of different ages and metallicities, but the data should be valuable for stellar studies in the Galaxy as well.

Several of the new indices appear to be promising indicators of metallicity for old stellar populations. A complete list of index data and atmospheric parameters is available in computer-readable form.
