# 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 16th Symposium on Nuclei in the Cosmos. A link to the meeting website can be found here.
