Line Lists for the A(2)Pi-X-2 Sigma(+) (Red) and B-2 Sigma(+)-X-2 Sigma(+) (Violet) Systems of Cn, (Cn)-C-13-N-14, and (Cn)-C-12-N-15, and Application To Astronomical Spectra

Sneden, Christopher; Lucatello, Sara; Ram, Ram S.; Brooke, James S. A.; Bernath, Peter (2014-10)

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

X-Shooter Observations of Main-Sequence Stars in the Globular Cluster NGC 2808: First Chemical Tagging of A He-Normal and A He-Rich Dwarf

Bragaglia, A.; Carretta, E.; Gratton, R. G.; Lucatello, Sara; Milone, A.; Piotto, G.; D'Orazi, V.; Cassisi, S.; Sneden, Christopher; Bedin, L. R. (2010-09)

We present the first chemical composition study of two unevolved stars in the globular cluster NGC 2808, obtained with the X-shooter spectrograph at VLT.NGC 2808 shows three discrete, well-separated main sequences. The ...
