Emission of Radiation from Model Hydrogen Chromospheres

Abstract

On the basis of earlier work of Giovanelli (1949), the characteristics of the radiation fields of Ha, La, Lß, and the Lyman continuum have been calculated for model solar atmospheres consisting of a photosphere and an overlying chromosphere which scatters coherently, and which is isothermal at one of a number of kinetic temperatures in the range 1 × 104 to 2·5×l05 ºK.
