Fig. A.1.From: Dust formation history of galaxies: A critical role of metallicity* for the dust mass growth by accreting materials in the interstellar mediumTime evolution of the ratio of dust mass produced by stars to metal mass ejected by stars. Solid, dotted and dashed lines represent τSF = 0.5,5,50 Gyr, respectively. For comparison, the results of Fig. 2 with thin lines are overlaid on the panel. Cross symbols mark the switching point for each τSF.Back to article page
