Scientific paper

It is shown that the best agreement with recent experimental results is obtained for the model atmosphere of Vega with parameters: Teff = 9590K and log g = 3.95. It is found that the measured fluxes are in excess over the model atmosphere calculations for wavelengths beyond 1 μm. This excess is not due to short wavelength radiation from the dust cloud around Vega.
