Subject: Origin of Short-Lived Isotopes in the Early Solar System

Understanding the origin of the short-lived radio isotopes (SLR) that were present in the early solar system (ESS) is crucial in understanding the events leading to the formation of the Solar System. Many of the SLR require a nucleosynthetic event within about a million years before the formation of the Solar System. We show that low mass compact progenitors of can self-consistently account of some of the very short-lived isotopes such as ^{41} Ca, ^{53} Mn, and ^{60} Fe. Furthermore, neutrino-induced spallation can also account for ^{10} Be in the ESS, which until now were thought to be produced only by cosmic ray irradiation.
