r-Process nucleosynthesis in material ejected during neutron star mergers may lead to radioactively powered transients called kilonovae. The timescale and peak luminosity of these transients depend on the composition of the ejecta, which determines the local heating rate from nuclear decays and the opacity. Kasen et al. (2013, ApJ, 774, 25) and Tanaka & Hotokezaka (2013, ApJ, 775, 113) pointed out that lanthanides can drastically increase the opacity in these outflows. We use the new general…

Radioactive energies from unstable nuclei made in the ejecta of neutron star mergers play principal roles in powering kilonovae. In previous studies power-law-type heating rates (e.g., ~ t^-1.3) have
Analytic heating rate of neutron star merger ejecta derived from Fermi's theory of beta decay
Macronovae (kilonovae) that arise in binary neutron star mergers are powered by radioactive beta decay of hundreds of $r$-process nuclides. We derive, using Fermi's theory of beta decay, an analytic
Fingerprints of Heavy-Element Nucleosynthesis in the Late-Time Lightcurves of Kilonovae.
It is found that the yet-uncertain r abundance of ^{72}Ge plays a decisive role in powering the lightcurve of AT2017gfo, if one assumes that GW170817 has produced a full range of the solar r abundances down to mass number A∼70.
Radioactive Heating Rate of r-process Elements and Macronova Light Curve
We study the heating rate of r-process nuclei and thermalization of decay products in neutron star merger ejecta and macronova (kilonova) light curves. Thermalization of charged decay products, i.e.,
Kilonovae Across the Nuclear Physics Landscape: The Impact of Nuclear Physics Uncertainties on r-process-powered Emission
Merging neutron stars produce “kilonovae”—electromagnetic transients powered by the decay of unstable nuclei synthesized via rapid neutron capture (the r-process) in material that is gravitationally
Radioactive Heating and Late Time Kilonova Light Curves
Compact object mergers can produce a thermal electromagnetic counterpart (a "kilonova") powered by the decay of freshly synthesized radioactive isotopes. The luminosity of kilonova light curves
Systematic opacity calculations for kilonovae
Coalescence of neutron stars (NSs) gives rise to kilonova, thermal emission powered by radioactive decays of freshly synthesized r-process nuclei. Although observational properties are largely
Production of the entire range of r-process nuclides by black hole accretion disc outflows from neutron star mergers
We consider $r$-process nucleosynthesis in outflows from black hole accretion discs formed in double neutron star and neutron star -- black hole mergers. These outflows, powered by angular momentum
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 binary
Fission and the r -process nucleosynthesis of translead nuclei in neutron star mergers
We study the impact of fission on the production and destruction of translead nuclei during the r-process nucleosynthesis occurring in neutron star mergers. Abundance patterns and rates of nuclear


Opacities and Spectra of the $r$-process Ejecta from Neutron Star Mergers
Material ejected during (or immediately following) the merger of two neutron stars may assemble into heavy elements through the r-process. The subsequent radioactive decay of the nuclei can power
R-process nucleosynthesis in dynamically ejected matter of neutron star mergers
Although the rapid neutron-capture process, or r-process, is fundamentally important for explaining the origin of approximately half of the stable nuclei with A > 60, the astrophysical site of this
Production of all the r-process nuclides in the dynamical ejecta of neutron star mergers
Recent studies suggest that binary neutron star (NS-NS) mergers robustly produce heavy r-process nuclei above the atomic mass number A ~ 130 because their ejecta consist of almost pure neutrons
r-Process in Neutron Star Mergers.
Sufficient material is ejected to explain the amount of r-process nuclei in the Galaxy by decompression of neutron star material, and the calculated abundances fit the observed solar r-pattern excellently for nuclei that include and are heavier than the A approximately 130 peak.
Neutron-powered precursors of kilonovae
The merger of binary neutron stars (NSs) ejects a small quantity of neutron-rich matter, the radioactive decay of which powers a day to week long thermal transient known as a kilonova. Most of the

We present a comprehensive study of r-process element nucleosynthesis in the ejecta of compact binary mergers (CBMs) and their relic black-hole (BH)-torus systems. The evolution of the BH-accretion
On the astrophysical robustness of the neutron star merger r-process
In this study we explore nucleosynthesis in the dynamic ejecta of compact binary mergers. We are particularly interested in the question how sensitive the resulting abundance patterns are to the

We use results from long-time core-collapse supernovae simulations to investigate the impact of the late time evolution of the ejecta and of the nuclear physics input on the calculated r-process
