Proposed Lunar Measurements of -Process Radioisotopes to Distinguish Origin of Deep-sea 244Pu
Xilu Wang, Adam M. Clark, John Ellis +6
244Pu has recently been discovered in deep-sea deposits spanning the past 10 Myr, a period that includes two 60Fe pulses from nearby supernovae. 244Pu is among the heaviest -pro…
Simulations of Fe entrained in ejecta from a near-Earth supernova: Effects of observer motion
Evgenii Chaikin, Alexander A. Kaurov, Brian D. Fields +1
Recent studies have shown that live (not decayed) radioactive Fe is present in deep-ocean samples, Antarctic snow, lunar regolith, and cosmic rays. Fe represents supe…
r-Process Radioisotopes from Near-Earth Supernovae and Kilonovae
Xilu Wang, Adam M. Clark, John Ellis +5
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-col…
