Supra-Canonical Initial 26Al/27Al Indicate a 105 Year Residence Time for CAIs in the Solar Proto-Planetary Disk
Abstract
We present new UV laser ablation and acid digestion MC-ICPMS analyses of 8 CAIs showing that there was more 26Al in the early solar system than previously thought, and that the canonical initial 26Al/27Al represents a ~300,000 yr residence time for CAIs in the protoplanetary disk.
