The dependence of the energy distribution on the abundances of A-star atmosphere models
Abstract
We calculated the energy distributions of A-star atmospheres ({Teff=10 000} K,{log g=4.0}) for ranges of the abundances of silicon and other light chemical elements using adequate model atmospheres. We discuss the reasons for and the magnitudes of the calculated departures of the stellar energy distribution and uvby magnitudes from those of normal stars.
