Panel A: SFR as the function of the Galactic time. Panel B: time evolution of the [Fe/H] abundances with the two-infall chemical evolution model for the Milky Way disk (the “age-metallicity” relation). Panel C: evolution in time of the type II SN rates plus the type Ia SN rates. With the red line we show the quantity 2 × ⟨ RSN_SV ⟩ , which represents the minimum SN rate value (adopted in this work and in Paper I) for destruction effects from SN explosions. Panel D: time evolution of the total dust surface mass density. The color code in the four panels indicates the different Galactocentric distances.
