Supernova Nanoparticles are the Carriers of ^(54)Cr Anomalies in Planetary Materials


Acid leachates and residues of primitive meteorites have revealed large variations in ^(54)Cr relative to terrestrial composition [1–9]. Despite two decades of extensive search, the nature of the carrier of ^(54)Cr excesses is still uncertain. Ion probes offer the opportunity to address directly this question by measuring ^(54)Cr/^(52)Cr ratios in individual grains [10–13].
