Isotopic Enrichment of Planetary Systems from Asymptotic Giant Branch Stars
Short-lived radioisotopes, in particular ^26 Al and ^60 Fe, are thought to contribute to the internal heating of the Earth, but are significantly more abundant in the solar system compared to the interstellar medium. The presence of their decay products in the oldest solar system objects argues for...
