Comprehensive nucleosynthesis analysis for ejecta of compact binary mergers [PDF]
, 2014 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 Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Groove formation on Phobos from reimpacting orbital ejecta of the Stickney crater
Earth and Planetary Physics, 2022 Numerous linear grooves have long been recognized as covering the surface of Phobos, but the mechanisms of their formation are still unclear. One possible mechanism is related to the largest crater on Phobos, the Stickney crater, whose impact ejecta may ...

Nepheline-kalsilite microperthites in ejecta from the Alban Hills (Italy) [PDF]
Bulletin of the Geological Society of Finland, 1985 Microprobe analyses carried out on exsolved nepheline and kalsilite phases of microperthites occurring in three ejecta from the Alban Hills (Roman comagmatic region) have shown: (1) a practically continuous compositional variation from Ks to Ne (bulk ...

A Low-mass Binary Neutron Star: Long-term Ejecta Evolution and Kilonovae with Weak Blue Emission [PDF]
Astrophysical Journal, 2020 We study the long-term evolution of ejecta formed in a binary neutron star (NS) merger that results in a long-lived remnant NS by performing a hydrodynamics simulation with the outflow data of a numerical relativity simulation as the initial condition ...

Constraint on the Ejecta Mass for Black Hole–Neutron Star Merger Event Candidate S190814bv [PDF]
Astrophysical Journal, 2020 We derive the upper limit to the ejecta mass of S190814bv, a black hole–neutron star (BH–NS) merger candidate, through radiative transfer simulations for kilonovae with realistic ejecta density profiles, as well as detailed opacity and heating rate ...

A Magnetar Origin for the Kilonova Ejecta in GW170817 [PDF]
, 2018 The neutron star (NS) merger GW170817 was followed over several days by optical-wavelength (“blue”) kilonova (KN) emission likely powered by the radioactive decay of light r-process nuclei synthesized by ejecta with a low neutron abundance (electron ...

Production of Very Light Elements and Strontium in the Early Ejecta of Neutron Star Mergers [PDF]
Astrophysical Journal, 2020 We study the production of very light elements (Z < 20) in the dynamical and spiral-wave wind ejecta of binary neutron star mergers by combining detailed nucleosynthesis calculations with the outcome of numerical relativity merger simulations.
