The Magnesium Isotopologues of MgH in the A(2)Pi-X-2 Sigma(+) System
Using laboratory hollow cathode spectra we have identified lines of the less common magnesium isotopologues of MgH, (MgH)-Mg-25 and (MgH)-Mg-26, in the A(2)Pi-X-2 Sigma(+) system. Based on the previous analysis of (MgH)-Mg-24, ...
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
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 ...
Chemical Abundances For Evolved Stars In M5: Lithium Through Thorium
We present analysis of high-resolution spectra of a sample of stars in the globular cluster M5 (NGC 5904). The sample includes stars from the red giant branch (RGB; seven stars), the red horizontal branch (two stars), and ...
Searching For Chemical Signatures Of Multiple Stellar Populations In The Old, Massive Open Cluster NGC 6791
Galactic open and globular clusters (OCs, GCs) appear to inhabit separate regions of the age-mass plane. However, the transition between them is not easily defined because there is some overlap between high-mass, old OCs ...
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
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 ...
Improved Line Data for the Swan System (Cc)-C-12-C-13 Isotopologue
We present new, accurate predictions for rotational line positions, excitation energies, and transition probabilities of the (CC)-C-12-C-13 isotopologue Swan d(3)Pi-a(3)Pi system 0-0, 0-1, 0-2, 1-0, 1-1, 1-2, 2-0, 2-1, and ...
