Fig. 2.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 fraction of metals in dust, δ with η = 1.00. Solid, dotted and dashed lines represent τSF = 0.5, 5, 50 Gyr, respectively. Cross symbols mark the switching point for each τSF.Back to article page
