Theoretical Line Intensities. V. Solar UV Emission Lines of Heavy Elements

Abstract

Analysis of the solar ultraviolet emission lines for eleven elements heavier than helium yields values for relative abundances and a relationship between T and dT dk in the chromosphere-corona transition region. The derived abundances, with the single exception of oxygen, are within 30 per cent of the photo- spheric abundances found by Goldberg, Mtiller, and Aller. Oxygen is found to have a relative abundance about one-half as large as the photospheric value. In the chromosphere-corona transition T '12dT /dh is constant with height, corresponding to a constant flux of coiiducted energy.
