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. © 2014. The American Astronomical Society.
