Extended Data Fig. 5: Total accreted mass of Earth material (from the best-fitting model) as a function of Δln(Z) between the planetary ingestion and the flat models for the 91 close, co-natal co-moving pairs.
From: At least one in a dozen stars shows evidence of planetary ingestion
The dashed line marks out our selection criterion for Δln(Z). The data are colour-coded with the mass fraction of convection zone (fCZ), indicating that stars with larger Δln(Z) tend to have larger accreted mass, while the exact amount of accretion is determined by fCZ.
