Early solar system radioactivity and AGB stars

Abstract

The possible stellar origin of those short-lived nuclei that were shown to be alive in the Early Solar System (ESS) is briefly discussed. The applicability of a close-by AGB star polluting the protosolar nebula depends on the extent to which several nuclei can be explained and in particular the strongly debated problems of the initial amount of ^(60)Fe, as inferred from recent measurements.
