The Origin of r-Process Elements in the Milky Way
Some of the heavy elements, such as gold and europium (Eu), are almost exclusively formed by the rapid neutron capture process (r-process). However, it is still unclear which astrophysical siteExpand
The impact of individual nuclear properties on $r$-process nucleosynthesis
The astrophysical rapid neutron capture process or `$r$ process' of nucleosynthesis is believed to be responsible for the production of approximately half the heavy element abundances found inExpand
Fission barriers at the end of the chart of the nuclides
We present calculated fission-barrier heights for 5239 nuclides for all nuclei between the proton and neutron drip lines with 171 ≤ A ≤ 330. The barriers are calculated in the macroscopic-microscopicExpand
Formation of the rare-earth peak: Gaining insight into late-time r -process dynamics
We study the formation and final structure of the rare-earth peak ($A\ensuremath{\sim}160$) of the $r$-process nucleosynthesis. Under high-entropy conditions ($Sg100{k}_{B}$), the rare-earth peakExpand
Full Transport General Relativistic Radiation Magnetohydrodynamics for Nucleosynthesis in Collapsars
We model a compact black hole-accretion disk system in the collapsar scenario with full transport, frequency dependent, general relativistic radiation magnetohydrodynamics. We examine whether or notExpand
Californium-254 and Kilonova Light Curves
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 $r$-process. We haveExpand
Using excitation-energy dependent fission yields to identify key fissioning nuclei in r-process nucleosynthesis
We evaluate the impact of using sets of fission yields given by the GEF code for spontaneous (sf), neutron-induced ((n,f)), and beta-delayed (betadf) fission processes which take into account theExpand
Full transport model of GW170817-like disk produces a blue kilonova
The 2017 detection of the inspiral and merger of two neutron stars in gravitational waves and gamma rays was accompanied by a quickly-reddening transient. Such a transient was predicted to occurExpand
Precision Mass Measurements of Neutron-Rich Neodymium and Samarium Isotopes and Their Role in Understanding Rare-Earth Peak Formation.
These measurements are the first to push into the region of nuclear masses relevant to the formation of the rare-earth abundance peak at A∼165 by the rapid neutron-capture process and are consistent with the reverse-engineering predictions for a neutron star merger wind scenario. Expand
Gamma-rays from kilonova: a potential probe of r-process nucleosynthesis
The mergers of compact binaries with at least one neutron star component are the potential leading sites of the production and ejection of $r$-process elements. Discoveries of galactic binaryExpand
