Astromers in the radioactive decay of r-process nuclei

G. Wendell Misch, T. M. Sprouse, M. R. Mumpower

We study the impact of astrophysically relevant nuclear isomers (astromers) in the context of the rapid neutron capture process (r-process) nucleosynthesis. We compute thermally me…

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…

Reconstructing Masses of Merging Neutron Stars from Stellar -Process Abundance Signatures

Erika M. Holmbeck, Anna Frebel, G. C. McLaughlin +5

Neutron star mergers (NSMs) are promising astrophysical sites for the rapid neutron-capture ("-") process, but can their integrated yields explain the majority of heavy-element…

Following nuclei through nucleosynthesis: a novel tracing technique

T. M. Sprouse, M. R. Mumpower, R. Surman

Astrophysical nucleosynthesis is a family of diverse processes by which atomic nuclei undergo nuclear reactions and decays to form new nuclei. The complex nature of nucleosynthesis…

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…

-Decay Half-Lives of 55 Neutron-Rich Isotopes beyond the N=82 Shell Gap

J. Wu, S. Nishimura, P. Möller +48

The -decay half-lives of 55 neutron-rich nuclei Sn, Sb, Te, I, Xe, Cs, Ba, La wer…

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…
