Element abundance patterns in stars indicate fission of nuclei heavier than uranium
Ian U. Roederer, Nicole Vassh, Erika M. Holmbeck +9
The heaviest chemical elements are naturally produced by the rapid neutron-capture process (r-process) during neutron star mergers or supernovae. The r-process production of elemen…
Evidence for multiple nucleosynthetic processes from carbon enhanced metal-poor stars in the Carina dwarf spheroidal galaxy
T. T. Hansen, J. D. Simon, T. S. Li +3
Context: Carbon Enhanced Metal-Poor (CEMP) stars () are known to exist in large numbers at low metallicity in the Milky Way halo and are important tracers of…
Raising the observed metallicity floor with a 3D non-LTE analysis of SDSS J102915.14+172927.9
C. Lagae, A. M. Amarsi, L. F. Rodríguez Díaz +4
Context: The first stars produced the first heavy elements and set the stage for the formation of the first galaxies. Accurate chemical abundances of ultra metal-poor stars ([Fe/H]…
Uranium Abundances and Ages of -process Enhanced Stars with Novel U II Lines
Shivani P. Shah, Rana Ezzeddine, Alexander P. Ji +7
The ages of the oldest stars shed light on the birth, chemical enrichment, and chemical evolution of the Universe. Nucleocosmochronometry provides an avenue to determining the ages…
