Fig. 7.From: Dust formation history of galaxies: A critical role of metallicity* for the dust mass growth by accreting materials in the interstellar mediumThe relation between metallicity and dust-to-gas mass ratio for ā = 0.1 μm (solid line) and 0.01 μm (dotted line) with τSF = 5 Gyr and η = 1.00. From Eq. (27), Zcr (0.01 μm) ~ 0.32 Zcr (0.1 μm).Back to article page
