Journal ArticleDOI
Neutron-Capture Elements in the Early Galaxy: Insights from a Large Sample of Metal-poor Giants
Debra L. Burris,Catherine A. Pilachowski,Taft E. Armandroff,Christopher Sneden,John J. Cowan,Henry G. Roe +5 more
TL;DR: In this article, a large sample of metal-poor giants from the Bond survey is presented, and the abundances of eight n-capture elements (Sr, Y, Zr, Ba, La, Nd, Eu, and Dy) in 43 stars have been derived from blue and red spectra.
Journal ArticleDOI
Barium and Sodium Abundances in the Globular Clusters M15 and M92
TL;DR: In this article, the upper giant branch members of the Galactic globular clusters M15 and M92 have been surveyed with the WIYN 3.5 m telescope and Hydra multiobject fiber-fed spectrometer.
Journal ArticleDOI
Europium, samarium, and neodymium isotopic fractions in metal-poor stars
Ian U. Roederer,James E. Lawler,Christopher Sneden,John J. Cowan,Jennifer Sobeck,Jennifer Sobeck,Catherine A. Pilachowski +6 more
TL;DR: In this article, isotopic fractions of europium, samarium, and neodymium in two metal-poor giants with differing neutron-capture nucleosynthetic histories were derived from new high-resolution (R ~ 120,000), high signal-to-noise ratio (S/N ~ 160-1000) spectra obtained with the 2d-coude spectrograph of McDonald Observatory's 2.7 m Smith telescope.
Journal ArticleDOI
A Survey for Enhanced Lithium in 261 Globular Cluster Giants
Catherine A. Pilachowski,Christopher Sneden,Robert P. Kraft,Dianne Harmer,Daryl W. Willmarth +4 more
TL;DR: A survey of 261 giants in the globular clusters M3, M13, M15, and M92 carried out with the Hydra multiobject spectrograph on the WIYN 3.5 m telescope has identified no stars with Li I 6707 A resonance lines stronger than 20 mA as mentioned in this paper.
Journal ArticleDOI
Limits on line bisector variability for stars with extrasolar planets
Matthew S. Povich,Mark S. Giampapa,Jeff A. Valenti,Jeff A. Valenti,T. Tilleman,S. Barden,Drake Deming,W. C. Livingston,Catherine A. Pilachowski +8 more
TL;DR: In this article, the authors present an analysis of high-resolution synoptic spectra of ten F and G-type stars, seven of which exhibit periodic radial velocity variations due to the presence of one or more substellar companions.
