Physicists Uncover How Stars Create Heavy Elements

TL;DR
Scientists at Michigan's FRIB are experimentally recreating how heavy elements beyond iron are formed in stars, focusing on the intermediate neutron-capture process (i-process), which fills gaps in understanding of element formation like gold and platinum, using advanced isotope experiments to identify where and how these processes occur in stellar environments.
