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…
Using excitation-energy dependent fission yields to identify key fissioning nuclei in r-process nucleosynthesis
Nicole Vassh, Ramona Vogt, Rebecca Surman +8
We evaluate the impact of using sets of fission yields given by the GEF code for spontaneous (sf), neutron-induced ((n,f)), and beta-delayed (betadf) fission processes which take i…
FRIB and the GW170817 Kilonova
A. Aprahamian, R. Surman, A. Frebel +45
In July 2018 an FRIB Theory Alliance program was held on the implications of GW170817 and its associated kilonova for r-process nucleosynthesis. Topics of discussion included the a…
Elastic Scattering in General Relativistic Ray Tracing for Neutrinos
M. Brett Deaton, Evan O'Connor, Y. L. Zhu +5
We present a covariant ray tracing algorithm for computing high-resolution neutrino distributions in general relativistic numerical spacetimes with hydrodynamical sources. Our form…
Californium-254 and kilonova light curves
Y. Zhu, R. T. Wollaeger, N. Vassh +13
Neutron star mergers offer unique conditions for the creation of the heavy elements and additionally provide a testbed for our understanding of this synthesis known as the -proc…
