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 carbon-enhanced metal-poor stars HD 196944 and HD 201626. When lines of 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 generally are also in accord with published values.

    Abundances and Ba isotopic ratios in TYC 6044-714-1 are best reproduced by s+r nucleosynthesis models; i+s+r models require extreme conditions and fail to match the full pattern.

    High-precision abundances and Ba isotopic ratios in TYC 6044-714-1 favor an s+r nucleosynthesis scenario over i-process models, which require implausible conditions and mismatch isotopic data.
