On the Use of Field RR Lyrae as Galactic Probes. III. The -element abundances
J. Crestani, V. F. Braga, M. Fabrizio +33
We provide the largest and most homogeneous sample of -element (Mg, Ca, Ti) and iron abundances for field RR Lyrae (RRLs, 162 variables) by using high-resolution spectra. The cu…
Discovery of a Metal-Poor Field Giant with a Globular Cluster Second-Generation Abundance Pattern
J. G. Fernández-Trincado, A. C. Robin, E. Moreno +31
We report on detection, from observations obtained with the APOGEE spectroscopic survey, of a metal-poor ([Fe/H] dex) field giant star with an extreme Mg-Al abundance rati…
The case of the disappearing CN-strong AGB stars in Galactic globular clusters -- Preliminary Results
S. W. Campbell, D. Yong, E. C. Wylie-de Boer +5
A previously reported literature search suggested that the AGB stars in Galactic globular clusters may be showing different distributions of CN-strong and CN-weak stars as compared…
The End of Nucleosynthesis: Production of Lead and Thorium in the Early Galaxy
Ian U. Roederer, Karl-Ludwig Kratz, Anna Frebel +4
We examine the Pb and Th abundances in 27 metal-poor stars (-3.1 < [Fe/H] < -1.4) whose very heavy metal (Z > 56) enrichment was produced only by the rapid (r-) nucleosynthesis pro…
The SEGUE Stellar Parameter Pipeline. III. Comparison with High-Resolution Spectroscopy of SDSS/SEGUE Field Stars
C. Allende Prieto, T. Sivarani, T. C. Beers +14
We report high-resolution spectroscopy of 125 field stars previously observed as part of the Sloan Digital Sky Survey and its program for Galactic studies, the Sloan Extension for…
Galactic Evolution of Sr, Y, Zr: A Multiplicity of Nucleosynthetic Processes
Claudia Travaglio, Roberto Gallino, Enrico Arnone +3
We follow the Galactic enrichment of three easily observed light n-capture elements Sr,Y,and Zr.Input stellar yields have been first separated into their respective main and weak s…
