High-resolution synthetic stellar library

In this paper, a new library of high resolution synthetic spectra is presented, ranging from the near-ultraviolet (300nm) to the near-infrared (1.8{mu}m). The library spans all the stellar types that are relevant to the integrated light of old and intermediate-age stellar populations in the involved spectral region (spectral types F through M and all luminosity classes).

The grid was computed for metallicities ranging from [Fe/H]=-2.5 to +0.5, including both solar and {alpha}-enhanced ([{alpha}/Fe]=0.4) chemical compositions. The synthetic spectra are a good match to observations of stars throughout the stellar parameter space encompassed by the library and over the whole spectral region covered by the computations.
