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…

The need for a local nuclear physics feature in the neutron-rich rare-earths to explain solar -process abundances

Nicole Vassh, Gail C. McLaughlin, Matthew R. Mumpower +1

We apply Markov Chain Monte Carlo to predict the masses required to form the observed solar -process rare-earth abundance peak. Given highly distinct astrophysical outflows and…

Kilonovae across the nuclear physics landscape: The impact of nuclear physics uncertainties on r-process-powered emission

Jennifer Barnes, Y. L. Zhu, K. A. Lund +5

Merging neutron stars produce "kilonovae"---electromagnetic transients powered by the decay of unstable nuclei synthesized via rapid neutron capture (the r-process) in material tha…

Modeling Kilonova Light Curves: Dependence on Nuclear Inputs

Y. L. Zhu, K. Lund, J. Barnes +5

The mergers of binary neutron stars, as well as black hole-neutron star systems, are expected to produce an electromagnetic counterpart that can be analyzed to infer the element sy…

MeV Gamma Rays from Fission: A Distinct Signature of Actinide Production in Neutron Star Mergers

Xilu Wang, Nicole Vassh, Trevor Sprouse +4

Neutron star mergers (NSMs) are the first verified sites of rapid neutron capture (r-process) nucleosynthesis, and could emit gamma rays from the radioactive isotopes synthesized i…

Probing the fission properties of neutron-rich actinides with the astrophysical process

Nicole Vassh, Matthew R. Mumpower, Trevor M. Sprouse +2

We review recent work examining the influence of fission in rapid neutron capture (-process) nucleosynthesis which can take place in astrophysical environments. We briefly discu…
