Time evolution of the CAI abundance throughout the disk. CAIs are created in the innermost disk and efficiently transported outward, where they are diluted with new infalling population 1 dust. As they start drifting inward in the post-infall phase, a double peak profile develops. CAIs are piling up in Jupiter’s pressure bump as well as in the far outer disk, when they are slowed down by the increasing gas density. The two peaks eventually merge in the pressure bump.
