Heavy element abundances in giant stars of the globular clusters M4 and M5
David Yong, Amanda I. Karakas, David L. Lambert +2
We present a comprehensive abundance analysis of 27 heavy elements in bright giant stars of the globular clusters M4 and M5 based on high resolution, high signal-to-noise ratio spe…
Chemical abundances in giants stars of the tidally disrupted globular cluster NGC 6712 from high-resolution infrared spectroscopy
David Yong, Jorge Melendez, Katia Cunha +3
We present abundances of C, N, O, F, Na, and Fe in six giant stars of the tidally disrupted globular cluster NGC 6712. The abundances were derived by comparing synthetic spectra wi…
Rotation and Macroturbulence in Metal-poor Field Red Giant and Red Horizontal Branch Stars
Bruce W. Carney, David F. Gray, David Yong +4
We report the results for rotational velocities, Vrot sin i, and macroturbulence dispersion, zeta(RT), for 12 metal-poor field red giant branch stars and 7 metal-poor field red hor…
An abundance analysis of bright giants in the globular cluster NGC 1851
David Yong, Frank Grundahl
We present the chemical compositions for eight bright giants in the globular cluster NGC 1851. Our analysis reveals large star-to-star abundance variations and correlations of the…
Rubidium and lead abundances in giant stars of the globular clusters M4 and M5
David Yong, David L. Lambert, Diane B. Paulson +1
We present measurements of the neutron-capture elements Rb and Pb for bright giants in the globular clusters M4 and M5. The clusters are of similar metallicity ([Fe/H] = -1.2) but…
Chemical Composition of the Planet-Harboring Star TrES-1
A. Sozzetti, D. Yong, B. W. Carney +3
We present a detailed chemical abundance analysis of the parent star of the transiting extrasolar planet TrES-1. Based on high-resolution Keck/HIRES and HET/HRS spectra, we have de…
