Abstract
Libraries of stellar spectra are one of the main ingredients of stellar population synthesis models. Theoretical libraries have been increasingly used in recent years to overcome limitations of empirical libraries, in particular to explore parameter space (in temperatures, metalicities and abundance patterns) not well covered by empirical libraries. In this talk, a new theoretical stellar library is presented. It consists of high and low-resolution spectra which cover the parameter space required to the modelling of stellar populations between 30 Myr and 14 Gyr, metalicities Z between 0.0017 and 0.0048, at both solar-scaled and α-enhanced compositions. The characteristics of the library as well as comparisons to observations will be presented.
