Table 3

Variation in [Fe/H] caused by engulfment of 2,5, and 10 M_⊕ at 60 Myr and 4.5 Gyr, and evolution of the chemical signature after 1 Gyr and 3 Gyr.

Notes. Considering a threshold of σ_[Fe/H] = 0.02 dex or a more conservative threshold of σ_[Fe/H] = 0.06 dex affects which events would be detectable.
