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…
Measurement of the stellar NiNi cross section with AMS
Peter Ludwig, Georg Rugel, Iris Dillmann +10
The NiNi cross section was measured with a combination of the activation technique and accelerator mass spectrometry (AMS). The neutron activations were performe…
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…
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…
New attempts to understand nanodiamond stardust
Ulrich Ott, Astrid Besmehn, Khalil Farouqi +5
We report on a concerted effort aimed at understanding the origin and history of the pre-solar nanodiamonds in meteorites including the astrophysical sources of the observed isotop…
Determination of the stellar (n,gamma) cross section of 40Ca with accelerator mass spectrometry
I. Dillmann, C. Domingo-Pardo, M. Heil +11
The stellar (n,gamma) cross section of 40Ca at kT=25 keV has been measured with a combination of the activation technique and accelerator mass spectrometry (AMS). This combination…
