Research output: Contribution to conferenceAbstract


A critical constraint on solar system formation is the high abundance of 26Al (t1/2=0.7 Myr), ~17 times larger than the average ISM abundance at solar system birth from gamma-ray astronomy [1,2,3,6]. The abundance of 26Al as inferred in meteorites is too high [4,5,6] to be accounted for by long-term Galactic chemical evolution [7, 4, 8] or early solar system particle irradiation [9, 10].
