Description There are many different opacity sources in stellar atmospheres. Because of limited computational time and memory the less important opacity sources are usu- ally neglected in stellar atmosphere models. Rayleigh scattering is one of such opacities that are frequently neglected in model atmospheres. But this neglect is not valid for all cases. We study influence of Rayleigh scattering by hydrogen and helium on computed stellar atmospheres of hot stars with solar chemical composition and some types of chemically peculiar stars.
