Recent nucleosynthesis in the solar neighbourhood, detected with live radionuclides

In this article we try to summarize all information, gathered in the last three decades, on short-lived (order of Myr) radionuclides found in the Solar System with interstellar origin, most probably due to stellar processes like supernovae. The most important isotope is 60 Fe, but we discuss also in...

Description
Summary:In this article we try to summarize all information, gathered in the last three decades, on short-lived (order of Myr) radionuclides found in the Solar System with interstellar origin, most probably due to stellar processes like supernovae. The most important isotope is 60 Fe, but we discuss also information on 26 Al, 244 Pu and 53 Mn. We describe the environment of the Solar System during the past ≈ 10 Myr as well as the likely locations where the supernovae occured. Confirming evidence has been found in the composition and energy distribution of galactic cosmic rays. Finally, we discuss the effects that the recent supernova activity might have had on Earth’s climate and biosphere.
