Libraries of stellar spectra are fundamental tools for the study
of stellar populations, and both
empirical and synthetic libraries have been used for this purpose.
In this paper, a new library of high resolution synthetic spectra is presented,
ranging from the near-ultraviolet (300 nm) to the near-infrared
(1.8 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 α-enhanced ([ α/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.
