A Grid of Synthetic Stellar UV Fluxes

We present preliminary results of a large project aimed at creating an extended theoretical and observational database of stellar spectra in the ultraviolet wavelength range. This library will consist of IUE spectra at low and high resolution, and a set of LTE and NLTE theoretical fluxes. A first grid of 50 model fluxes with solar metallicity, in the wavelength interval 1000–4400 A, is reported here. Calculations are based on the Kurucz (1993) SYNTHE code. The models span effective temperatures between 10000 K and 50000 K, and a surface gravity in the range 2.5 ≤ log g ≤ 5.0 dex.
