Isotopic ratios for C, N, Si, Al, and Ti in C-rich presolar grains from massive stars
Jordan Schofield, Marco Pignatari, Richard J Stancliffe +1
Certain types of silicon carbide (SiC) grains, e.g., SiC-X grains, and low density (LD) graphites are C-rich presolar grains that are thought to have condensed in the ejecta of cor…
Barium stars as tracers of s-process nucleosynthesis in AGB stars II. Using machine learning techniques on 169 stars
J. W. den Hartogh, A. Yagüe López, B. Cseh +7
We aim to analyse the abundance pattern of 169 Barium (Ba) stars, using machine learning techniques and the AGB final surface abundances predicted by Fruity and Monash stellar mode…
The R-Process Alliance: Abundance Universality among Some Elements at and between the First and Second R-Process Peaks
Ian U. Roederer, John J. Cowan, Marco Pignatari +11
We present new observational benchmarks of rapid neutron-capture process (r-process) nucleosynthesis for elements at and between the first (A ~ 80) and second (A ~ 130) peaks. Our…
HD 222925: a New Opportunity to Explore the Astrophysical and Nuclear Conditions of r-process Sites
Erika M. Holmbeck, Rebecca Surman, Ian U. Roederer +2
With the most trans-iron elements detected of any star outside the Solar System, HD 222925 represents the most complete chemical inventory among r-process-enhanced, metal-poor star…
Chemo-Dynamically Tagged Groups of CEMP Stars in the Halo of the Milky Way. I. Untangling the Origins of CEMP- and CEMP-no Stars
Joseph Zepeda, Timothy C. Beers, Vinicius M. Placco +7
We construct a sample of 644 carbon-enhanced metal-poor (CEMP) stars with abundance analyses based on moderate- to high-resolution spectroscopic studies. Dynamical parameters for t…
Origin of Plutonium-244 in the Early Solar System
Maria Lugaro, Andrés Yagüe López, Benjámin Soós +5
We investigate the origin in the early Solar System of the short-lived radionuclide 244Pu (with a half life of 80 Myr) produced by the rapid (r) neutron-capture process. We conside…
