Caption: Figure 6.
Present day chemical disks' mass fraction per age bin. We use the previous definition of α-poor (blue) and α-rich (orange) populations to calculate their fraction contribution in each age bin. Colored dotted and dashed lines show the corresponding clumpy or nonclumpy isolated model counterpart. The time of the pericenter passage is indicated by the vertical gray dashed lines.
