We present an extended theoretical library of over 800 synthetic stellar spectra,
covering energy distribution in the optical range (λ = 3500-7000 Å),
at inverse resolution R=500,000. The library, based on the ATLAS9 model atmospheres,
has been computed with the SYNTHE code developed by R.L. Kurucz. The grid
spans a large volume in the fundamental parameters space (i.e. T_eff, log g, [M/H]),
and can be profitably applied to different research fields dealing both with
the study of single stars and stellar aggregates, through population synthesis models.
A complementary project, in progress, will extend the wavelength range to
the ultraviolet, down to 850 Å, at an inverse resolution of R=50,000. |
