Cosmic ray nucleosynthesis on Earth impactors
When a star explodes within a few hundred light-years of us, some of its material will travel to Earth. Recent detections of 60Fe in ocean sediment, cores, and even lunar samples from near-Earth supernova have prompted further investigation into how supernova material reaches Earth.
My current work asks the question "how else could the detected 60Fe have gotten here, if not from a supernova?" It turns out that cosmic ray nucleosynthesis can generate 60Fe on the surface of asteroids - should the asteroid fall to Earth, then we have 60Fe on Earth that did not come from a supernova. My research investigates this scenario to determine the likelihood of these impactors reproducing the 60Fe signal.
