Outward migration of chondrule fragments in the early Solar System: O-isotopic evidence for rocky material crossing the Jupiter Gap?

DL Schrader, K Nagashima, J Davidson… - … et Cosmochimica Acta, 2020 - Elsevier
Determining the origins of chondrule precursors is key to constraining how material migrated
