Numerical studies on the link between radioisotopic signatures on Earth and the formation of the Local Bubble. II. Advanced modeling of interstellar 26Al, 53Mn, 60Fe, and 244Pu influxes as traces of past supernovae in the solar neighborhood
Michael Mathias Schulreich, Jenny Feige, Dieter Breitschwerdt
Measurements of long-lived radioisotopes provide a means, completely independent of other observational channels, to draw conclusions about near-Earth supernovae (SNe) and thus the…
Near-Earth Supernova Explosions: Evidence, Implications, and Opportunities
Brian D. Fields, John R. Ellis, Walter R. Binns +36
There is now solid experimental evidence of at least one supernova explosion within 100 pc of Earth within the last few million years, from measurements of the short-lived isotope…
A Way Out of the Bubble Trouble? - Upon Reconstructing the Origin of the Local Bubble and Loop I via Radioisotopic Signatures on Earth
Michael Mathias Schulreich, Dieter Breitschwerdt, Jenny Feige +1
Deep-sea archives all over the world show an enhanced concentration of the radionuclide Fe, isolated in layers dating from about 2.2 Myr ago. Since this comparatively long-l…
Numerical studies on the link between radioisotopic signatures on Earth and the formation of the Local Bubble. I. 60Fe transport to the solar system by turbulent mixing of ejecta from nearby supernovae into a locally homogeneous ISM
Michael Mathias Schulreich, Dieter Breitschwerdt, Jenny Feige +1
The discovery of radionuclides like 60Fe with half-lives of million years in deep-sea crusts and sediments offers the unique possibility to date and locate nearby supernovae. We wa…
The Link Between the Local Bubble and Radioisotopic Signatures on Earth
Jenny Feige, Dieter Breitschwerdt, Anton Wallner +15
Traces of 2-3 Myr old 60Fe were recently discovered in a manganese crust and in lunar samples. We have found that this signal is extended in time and is present in globally distrib…
New limit of Pu on Earth points to rarity of actinide nucleosynthesis
A. Wallner, T. Faestermann, J. Feige +9
Half of the heavy elements including all actinides are produced in r-process nucleosynthesis whose sites and history still remain a mystery. If continuously produced, the Interstel…
AMS measurements of cosmogenic and supernova-ejected radionuclides in deep-sea sediment cores
J. Feige, A. Wallner, L. K. Fifield +6
Samples of two deep-sea sediment cores from the Indian Ocean are analyzed with accelerator mass spectrometry (AMS) to search for traces of recent supernova activity around 2 Myr ag…
The Search for Supernova-produced Radionuclides in Terrestrial Deep-sea Archives
Jenny Feige, Anton Wallner, Stephan R. Winkler +5
An enhanced concentration of 60Fe was found in a deep ocean's crust in 2004 in a layer corresponding to an age of ~2 Myr. The confirmation of this signal in terrestrial archives as…
