Integrated light models that incorporate common types of chemically peculiar (CP) stars are
assembled using synthetic spectra. Selected spectral features encode significant age …

Context. The integrated light of distant star clusters and galaxies can yield information on the
stellar formation epochs, chemical abundance mixtures, and initial stellar mass functions …

Determining the properties of old stellar populations (those with age> 1 Gyr) has long
involved the comparison of their integrated light, either in the form of photometry or …

We investigate the uncertainties in the synthetic integrated colors of simple stellar
populations, currently the most popular method of estimating the ages of unresolved stellar …

We present new FLAMES@ VLT spectroscopic observations of 30 stars in the field of the
Large Magellanic Cloud (LMC) stellar cluster NGC 1866. NGC 1866 is one of the few young …

We present new, high-to-intermediate spectral resolution stellar population models, based
on four popular libraries of empirical stellar spectra, namely Pickles, ELODIE, STELIB and …

The assembly history of the Milky Way (MW) is a rapidly evolving subject, with numerous
small accretion events and at least one major merger proposed in the MW's history. Accreted …

We present evolutionary population synthesis models for the study of the cool and luminous
intermediate age stellar populations in resolved galaxies with particular emphasis on carbon …

Context. The rest-frame near-IR spectra of intermediate age (1–2 Gyr) stellar populations are
dominated by carbon based absorption features offering a wealth of information. Yet …

Formation of globular clusters (GCs), the Galactic bulge, or galaxy bulges in general is an
important unsolved problem in Galactic astronomy. Homogeneous infrared observations of …
