Title: LINE LISTS FOR THE A {sup 2}Π-X {sup 2}Σ{sup +} (RED) AND B {sup 2}Σ{sup +}-X {sup 2}Σ{sup +} (VIOLET) SYSTEMS OF CN, {sup 13}C{sup 14}N, AND {sup 12}C{sup 15}N, AND APPLICATION TO ASTRONOMICAL SPECTRA

New red and violet system line lists for the CN isotopologues {sup 13}C{sup 14}N and {sup 12}C{sup 15}N have been generated. These new transition data are combined with those previously derived for {sup 12}C{sup 14}N, 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.
