244 Pu has recently been discovered in deep-sea deposits spanning the past 10 Myr, a period that includes two 60 Fe pulses from nearby supernovae. 244 Pu is among the heaviest r -process products, and we consider whether it was created in the supernovae, which is disfa-vored by nucleosynthesis simulations, or in an earlier kilonova event that seeded 244 Pu in the nearby interstellar medium that was subse-quently swept up by the supernova debris. We discuss how these possibilities can be probed…

r-Process Radioisotopes from Near-Earth Supernovae and Kilonovae

The astrophysical sites where r-process elements are synthesized remain mysterious: it is clear that neutron star mergers (kilonovae (KNe)) contribute, and some classes of core-collapse supernovae

Experimental Limit to Interstellar 244Pu Abundance

Short-lived nuclides, now extinct in the solar system, are expected to be present in the interstellar medium (ISM). Grains of ISM origin were recently discovered in the inner solar system and at

Supernova Dust Evolution Probed by Deep-Sea 60Fe Time History

There is a wealth of data on live, undecayed 60 Fe ( t 1 / 2 = 2 . 6 Myr) in deep-sea deposits, the lunar regolith, cosmic rays, and Antarctic snow, which is interpreted as originating from the

Abundance of live 244Pu in deep-sea reservoirs on Earth points to rarity of actinide nucleosynthesis

The detection of live interstellar 244Pu, archived in Earth’s deep-sea floor during the last 25 My, at abundances lower than expected from continuous production in the Galaxy by about 2 orders of magnitude may signal a rarity of actinide r-process nucleosynthesis sites, compatible with neutron-star mergers or with a small subset ofActinide-producing supernovae.

60Fe and 244Pu deposited on Earth constrain the r-process yields of recent nearby supernovae

The plutonium content of a deep-sea crust sample was analyzed, identifying a few dozen atoms of the r-process isotope plutonium- 244 that were delivered to Earth within the past few million years and comparing the ratios constrains the relative contributions of supernovae and neutron star mergers to r- Process nucleosynthesis.

Geological Isotope Anomalies as Signatures of Nearby Supernovae

Nearby supernova explosions may cause geological isotope anomalies via the direct deposition of debris or by cosmic-ray spallation in the earth's atmosphere. We estimate the mass of material

Recent near-Earth supernovae probed by global deposition of interstellar radioactive 60Fe

The findings indicate multiple supernova and massive-star events during the last ten million years at distances of up to 100 parsecs, which indicates that a few per cent of fresh 60Fe was captured in dust and deposited on Earth.

60Fe anomaly in a deep-sea manganese crust and implications for a nearby supernova source.

A well resolved time profile of the 60Fe concentration in a deep-sea ferromanganese crust is measured and a highly significant increase 2.8 Myr ago is found.
