Temporal evolution of the total number of FGK stars hosting minimum conditions for life (N_★,mHC) in the solar vicinity (black dashed lines). Both panels show the contribution from stars born in situ within the solar annulus (R_i = R_f = 8 kpc, dark blue lines) as well as those migrating from different Galactic regions (R_i ≠ R_f). We consider the case 2 SN destruction scenario in the presence of stellar migration, with radial migration strength of σ_RM = 3.5 kpc (model 3, upper panel) and σ_RM = 6 kpc (model 4, lower panel), respectively.
