Element abundance patterns in stars indicate fission of nuclei heavier than uranium
Ian U. Roederer, Nicole Vassh, Erika M. Holmbeck +9
The heaviest chemical elements are naturally produced by the rapid neutron-capture process (r-process) during neutron star mergers or supernovae. The r-process production of elemen…
Thallium-208: a beacon of in situ neutron capture nucleosynthesis
Nicole Vassh, Xilu Wang, Maude Lariviere +7
We demonstrate that the well-known 2.6 MeV gamma-ray emission line from thallium-208 could serve as a real-time indicator of astrophysical heavy element production, with both rapid…
Magnetic Field Strength Effects on Nucleosynthesis from Neutron Star Merger Outflows
Kelsey Alexandra Lund, Gail McLaughlin, Jonah Miller +1
Magnetohydrodynamic turbulence drives the central engine of post-merger remnants, potentially powering both a nucleosynthetically active disk wind and the relativistic jet behind a…
Emergent nucleosynthesis from a 1.2 second long simulation of a black-hole accretion disk
T. M. Sprouse, K. A. Lund, J. M. Miller +2
We simulate a black-hole accretion disk system with full-transport general relativistic neutrino radiation magnetohydrodynamics (GRRMHD) for 1.2 seconds. This system is likely t…
Superheavy Elements in Kilonovae
Erika M. Holmbeck, Jennifer Barnes, Kelsey A. Lund +3
As LIGO-Virgo-KAGRA enters its fourth observing run, a new opportunity to search for electromagnetic counterparts of compact object mergers will also begin. The light curves and sp…
Uncertainty Quantification of Mass Models using Ensemble Bayesian Model Averaging
Yukiya Saito, Iris Dillmann, Reiner Kruecken +2
Developments in the description of the masses of atomic nuclei have led to various nuclear mass models that provide predictions for masses across the whole chart of nuclides. These…
