Abstract
The main results of a program of systematic comparison between observed and computed UV spectral energy distributions of eld G-type stars are illustrated. We constructed the UV observed energy distributions for 53 G stars, starting from the IUE Uniform Low Dispersion Archive (ULDA) and computed the corresponding theoretical uxes by using the atmospheric parameters from the Catalogue of [Fe/H] Determinations (1996 edition) and a Kurucz grid of model uxes. From the comparison between observations and classical models, a UV excess shortward of 2000 is evident for all the program stars.
