Observed and computed UV spectral distribution of A and F stars.
Abstract
An automatic and fast procedure was implemented to determine Te and log g from the comparison of the UV S 2/68 spectra with the Kurucz models. The method has been applied to all A and F stars with (B-V)0 greater than or equal to 0 and luminosity classes III, IV, IV-V, and V, included in the Ultraviolet Bright-Star Spectrophotometric Catalogue. From the analysis, it appears that the models match the observed fluxes fairly well and that the effective temperatures derived from the UV data agree with those derived from Stromgren photometric indices within 200 K.
