The Curious Case of $^{60}$Fe in the Early Solar System

This invited talk reviews the discrepancies between in situ and bulk measurements of the initial ⁶⁰Fe abundance in the early Solar System. The abundance of this short-lived radionuclide is important to constrain precisely since it informs the source that contributed the ²⁶Al that was present in the solar nebula. The presentation discusses the new re-evaluation of the in-situ secondary ion mass spectrometry (SIMS) measurements and discusses the implications of this re-evaluation.

The talk was presented at the 16^th Symposium on Nuclei in the Cosmos. A link to the meeting website can be found here.
