Supernova Dust Evolution Probed by Deep-sea 60Fe Time History
Adrienne F. Ertel, Brian J. Fry, Brian D. Fields +1
There is a wealth of data on live, undecayed 60Fe () in deep-sea deposits, the lunar regolith, cosmic rays, and Antarctic snow, which is interpreted as ori…
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…
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…
Supernova Triggers for End-Devonian Extinctions
Brian D. Fields, Adrian L. Melott, John Ellis +6
The Late Devonian was a protracted period of low speciation resulting in biodiversity decline, culminating in extinction events near the Devonian-Carboniferous boundary. Recent evi…
Magnetic Imprisonment of Dusty Pinballs by a Supernova Remnant
Brian J. Fry, Brian D. Fields, John R. Ellis
Motivated by recent measurements of deposits of Fe on the ocean floor and the lunar surface, we model the transport of dust grains containing Fe from a near-Earth (i.…
Radioactive Iron Rain: Transporting Fe in Supernova Dust to the Ocean Floor
Brian J. Fry, Brian D. Fields, John R. Ellis
Several searches have found evidence of Fe deposition, presumably from a near-Earth supernova (SN), with concentrations that vary in different locations on Earth. This paper…
Astrophysical Shrapnel: Discriminating Among Near-Earth Stellar Explosion Sources of Live Radioactive Isotopes
Brian J. Fry, Brian D. Fields, John R. Ellis
We consider the production and deposition on Earth of isotopes with half-lives in the range 10 to 10 years that might provide signatures of nearby stellar explosions, e…
