The Origin of the Heaviest Metals in Most Ultra-Faint Dwarf Galaxies

Ian U. Roederer

The heaviest metals found in stars in most ultra-faint dwarf (UFD) galaxies in the Milky Way halo are generally underabundant by an order of magnitude or more when compared with st…

Neutron-Capture Element Abundances in Magellanic Cloud Planetary Nebulae

A. L. Mashburn, N. C. Sterling, S. Madonna +3

We present near-infrared spectra of ten planetary nebulae (PNe) in the Large and Small Magellanic Clouds (LMC and SMC), acquired with the FIRE and GNIRS spectrometers on the 6.5-m…

Observational Constraints on First-Star Nucleosynthesis. I. Evidence for Multiple Progenitors of CEMP-no Stars

Jinmi Yoon, Timothy C. Beers, Vinicius M. Placco +6

We investigate anew the distribution of absolute carbon abundance, (C) (C), for carbon-enhanced metal-poor (CEMP) stars in the halo of the Milky Way, based on high-re…

Detection of Phosphorus, Sulphur, and Zinc in the Carbon-Enhanced Metal-Poor Star BD+44 493

Ian U. Roederer, Vinicius M. Placco, Timothy C. Beers

The carbon-enhanced metal-poor star BD+44 493 ([Fe/H]=-3.9) has been proposed as a candidate second-generation star enriched by metals from a single Pop III star. We report the fir…

The Diverse Origins of Neutron-Capture Elements in the Metal-Poor Star HD 94028: Possible Detection of Products of i-process Nucleosynthesis

Ian U. Roederer, Amanda I. Karakas, Marco Pignatari +1

We present a detailed analysis of the composition and nucleosynthetic origins of the heavy elements in the metal-poor ([Fe/H]=-1.62+/-0.09) star HD94028. Previous studies revealed…
