Holmbeck The Looking-Glass and Beyond: Using Observations and Modeling of Stellar Actinide Abundances as a Window into r-Process Events 2020 .txt text/plain 219 7 37 I find that neutron star mergers have the potential to synthesize all observed levels of actinide abundances measured in metal-poor stars if astrophysical variations on the composition of the ejecta are allowed within the merger site. Using this principle, I then determine that if neutron star mergers produced the majority of r-process elements in the Galaxy, then the first mergers were primarily mass-asymmetric. cache/df65v69608r.txt txt/df65v69608r.txt
