Rosseland mean opacities of stellar atmospheres
Abstract
Calculations of Rosseland mean opacities in terms of hydrogen particle units are presented for solar type atmospheres. The sources of opacities under consideration include H(-), HI, H2(-), H2(+), He I, He II, C I, C II, C III, N I, N II, N III, O I, O II, Na I, Mg II, Al I, Al II, Si II, Cl I, K I, and Ca II in the absorption form. H I, He I, C I, N I, O I, and H2 were used as sources for Rayleigh scattering, and free electrons were studied in the form of Thomson scattering.
