Machine Learning -decay Half-lives and Their Application to -Process Observables
Mengke Li, Flora Wang, Jonathan Engel +4
Accurately modeling -decay half-lives of highly neutron-rich nuclei is a critical challenge for understanding -process nucleosynthesis and the resulting kilonova light curves…
Identifying observable MeV lines from the decays of weak and main -process isotopes in mergers
Maude Lariviere, Nicole Vassh, Yanwen Deng +2
We consider predictions for the MeV gamma-ray spectrum emitted by the decays of freshly synthesized isotopes from a neutron star merger at timescales of relevance for post-merg…
Multidisciplinary Science in the Multimessenger Era
Eric Burns, Christopher L. Fryer, Ivan Agullo +82
Astrophysical observations of the cosmos allow us to probe extreme physics and answer foundational questions on our universe. Modern astronomy is increasingly operating under a hol…
Nuclear uncertainties associated with the ejecta of a neutron-star black-hole accretion disk
M. R. Mumpower, T. M. Sprouse, J. M. Miller +5
The simulation of heavy element nucleosynthesis requires input from yet-to-be-measured nuclear properties. The uncertainty in the values of these off-stability nuclear properties p…
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…
Spallation of r-Process Nuclei Ejected from a Neutron Star Merger
Xilu Wang, Brian D. Fields, Matthew Mumpower +3
Neutron star mergers (NSMs) are rapid neutron capture (r-process) nucleosynthesis sites, which eject materials at high velocities, from 0.1c to as high as 0.6c. Thus the r-process…
Characterizing -Process Sites through Actinide Production
Erika M. Holmbeck, Rebecca Surman, Anna Frebel +6
Of the variations in the elemental abundance patterns of stars enhanced with -process elements, the variation in the relative actinide-to-lanthanide ratio is among the most sign…
Co-production of light and heavy -process elements via fission deposition
Nicole Vassh, Matthew R. Mumpower, Gail C. McLaughlin +2
We apply for the first time fission yields determined across the chart of nuclides from the macroscopic-microscopic theory of the Finite Range Liquid Drop Model to simulations of r…
Sandblasting the -Process: Spallation of Ejecta from Neutron Star Mergers
Xilu Wang, Brian D. Fields, Matthew Mumpower +3
Neutron star mergers (NSMs) are rapid neutron capture (-process) nucleosynthesis sites that expel matter at high velocities, from to as high as . Nuclei ej…
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…
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…
