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…
129I and 247Cm in Meteorites Constrain the Last Astrophysical Source of Solar r-process Elements
Benoit Côté, Marius Eichler, Andrés Yagüe +12
The composition of the early Solar System can be inferred from meteorites. Many elements heavier than iron were formed by the rapid neutron-capture process (r process), but the ast…
Markov Chain Monte Carlo Predictions of Neutron-rich Lanthanide Properties as a Probe of -process Dynamics
Nicole Vassh, Gail C. McLaughlin, Matthew R. Mumpower +1
Lanthanide element signatures are key to understanding many astrophysical observables, from merger kilonova light curves to stellar and solar abundances. To learn about the lanthan…
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…
