An Elemental Assay of Very, Extremely, and Ultra Metal-Poor Stars
T. Hansen, C. J. Hansen, N. Christlieb +8
We present a high-resolution elemental-abundance analysis for a sample of 23 very metal-poor (VMP; [Fe/H] < -2.0) stars, 12 of which are extremely metal-poor (EMP; [Fe/H] < -3.0),…
Nucleosynthesis in a Primordial Supernova: Carbon and Oxygen Abundances in SMSS J031300.36-670839.31
Michael Bessell, Remo Collett, Stefan Keller +15
SMSS J031300.36-670839.3 (hereafter SM0313-6708) is a sub-giant halo star, with no detectable Fe lines and large overabundances of C and Mg relative to Ca. We obtained VLT-UVES spe…
High-Resolution Spectroscopic Study of Extremely Metal-Poor Star Candidates from the SkyMapper Survey
Heather. R. Jacobson, Stefan Keller, Anna Frebel +13
The SkyMapper Southern Sky Survey is carrying out a search for the most metal-poor stars in the Galaxy. It identifies candidates by way of its unique filter set that allows for est…
Iron and s-elements abundance variations in NGC5286: comparison with anomalous globular clusters and Milky Way satellites
A. F. Marino, A. P. Milone, A. I. Karakas +13
We present a high resolution spectroscopic analysis of 62 red giants in the Milky Way globular cluster NGC5286. We have determined abundances of representative light proton-capture…
Near-Field Cosmology with Metal-Poor Stars
Anna Frebel, John E. Norris
The oldest, most metal-poor stars in the Galactic halo and satellite dwarf galaxies present an opportunity to explore the chemical and physical conditions of the earliest star form…
