Distances to Recent Near-Earth Supernovae From Geological and Lunar 60Fe
Adrienne F. Ertel, Brian D. Fields
Near-Earth supernova blasts which engulf the solar system have left traces of their ejecta in the geological and lunar records. There is now a wealth of data on live radioactive ${…
Near-Earth Supernovae in the Past 10 Myr: Implications for the Heliosphere
Jesse A. Miller, Brian D. Fields, Thomas Y. Chen +10
We summarize evidence that multiple supernovae exploded within 100 pc of Earth in the past few Myr. These events had dramatic effects on the heliosphere, compressing it to within ~…
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…
