Description
With the goal of assembling a new generation of more realistic single
stellar population (SSP) models, we have obtained magnesium abundances
for nearly 80% of the stars of the widely employed MILES empirical
spectral library. Additional spectroscopic observations of carefully
selected stars have recently been obtained to improve the parametric
coverage of this library. Here we report on: (i) the framework of Mg
abundance determination carried out at mid-resolution, (ii) the newly
acquired data, and (iii) the preliminary steps towards modelling stellar
populations.
