A large C+N+O abundance spread in giant stars of the globular cluster NGC 1851
David Yong, Frank Grundahl, Francesca D'Antona +3
Abundances of C, N, and O are determined in four bright red giants that span the known abundance range for light (Na and Al) and s-process (Zr and La) elements in the globular clus…
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…
Chemical similarities between Galactic bulge and local thick disk red giant stars
J. Melendez, M. Asplund, A. Alves-Brito +8
The evolution of the Milky Way bulge and its relationship with the other Galactic populations is still poorly understood. The bulge has been suggested to be either a merger-driven…
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…
