Abstract:
We have obtained [Mg/Fe] measurements for 76.3 per cent of the stars
in the Mid-resolution Isaac Newton Telescope Library of Empirical
Spectra (MILES) spectral library used for understanding stellar
atmospheres and stellar populations in galaxies and star clusters.
These abundance ratios were obtained through (1) a compilation of
values from the literature using abundances from high-resolution (HR)
spectroscopic studies and (2) a robust spectroscopic analysis using
the MILES mid-resolution (MR) optical spectra. All the [Mg/Fe] values
were carefully calibrated to a single uniform scale, by using an
extensive control sample with results from HR spectra.
