Title:Astronomical Applications Of New Line Lists For Cn, C2 And Their Isotopologues

Abstract:For cool stellar and substellar objects, atomic lines weaken, and detailed elemental and isotopic abundances are often derived from molecular absorption features. We have embarked on a project to provide molecular line lists by combining experimental observations for line positions with ab initio calculations for line strengths. So far we have results for MgH (A-X and B-X transitions)\footnote{E. GharibNezhad, A. Shayesteh and P. F. Bernath, Mon. Notices R. Astro. Soc. 432, 2043-2047 (2013)}\footnote{K. H. Hinkle, L. Wallace, R. S. Ram, P. F. Bernath, C. Sneden and S. Lucatello, Astrophys. J. Suppl. 207, 26 (7pp) (2013)}, C$_{2}$ (Swan system)\footnote{J. S. A. Brooke, P. F. Bernath, T. W. Schmidt and G. B. Bacskay, J. Quant. Spectrosc. Rad. Trans. 124, 11-20 (2013)}\footnote{R. S. Ram, J. S. A. Brooke, P. F. Bernath, C. Sneden and S. Lucatello, Astrophys. J. Suppl. 211, 5 (7pp) (2014)}, CN (red and violet systems)\footnote{J. S. A. Brooke, R. S. Ram, C. M. Western, G. Li, D. W. Schwenke and P. F. Bernath, Astrophys. J. Suppl. 210, 23 (15pp) (2014)}, CP (A-X transition)\footnote{R. S. Ram, J. S. A. Brooke, C.M. Western and P. F. Bernath, J. Quant. Spectrosc. Rad. Transfer (in press)}, NH (vibration-rotation bands) and OH (Meinel system)\footnote{J. S. A. Brooke et al., this meeting, P301}. This talk will briefly describe the new line lists for the Swan system (d$^{3}\Pi$-a$^{3}\Pi$) of C$_{2}$ and $^{12}$C$^{13}$C, and the red (A$^{2}\Pi$-X$^{2}\Sigma^{+}$) and violet (B$^{2}\Sigma^{+}$-X$^{2}\Sigma^{+}$) systems of CN, $^{13}$CN and C$^{15}$N. Applications to the spectra of carbon-enhanced metal-poor stars, the K-giant Arcturus, the metal-rich open cluster NGC 6791, the Sun and comets will be presented.
