Line Lists for the A 2Π-X 2Σ+ (Red) and B 2Σ+-X 2Σ+ (Violet) Systems of CN, 13C14N, and 12C15N, and Application to Astronomical Spectra
Abstract
New red and violet system line lists for the CN isotopologues 13C14N and 12C15N have been generated. These new transition data are combined with those previously derived for 12C14N, and applied to the determination of CNO abundances in the solar photosphere and in four red giant stars: Arcturus, the bright, very low-metallicity star HD 122563, and the carbon-enhanced metal-poor stars HD 196944 and HD 201626. When both red and violet system lines are detectable in a star, their derived N abundances are in good agreement. The mean N abundances determined in this work are also generally in accord with published values.
