Over the past years observations of young and populous star clusters have shown that the stellar initial mass function (IMF) can be conveniently described by a...

From the time the first stars formed to the present-day, metals have witnessed the assembly of structure in the Universe in great detail. Although metals only...

The basis of stellar population modeling was established around 40 years ago somehow optimized to the technical facilities and observational data available at...
