Evolution of the dust-to-gas and dust-to-metal mass ratios for EIT08M. The initial gas mass of the galaxy M_ini = 5 × 10¹¹ M_⊙. Calculations are performed for a “maximum” (top row), a “high” (middle row), and a “low” (bottom row) SN dust production efficiency ϵ_i(m). Dust destruction is taken into account for M_cl = 800   M_⊙ (left column), 100 M_⊙ (middle column), and 0 M_⊙ (right column). The upper group of curves signifies the dust-to-metal mass ratio η_Zd(t). The lower group of curves represents the dust-to-gas mass ratio η_d(t). The gas-to-dust ratio displayed in the figures is calculated for a Larson 2 IMF at an epoch of 400 Myr. The grey vertical dashed lines indicate epochs at 100, 400, and 500 Myr after the onset of starburst. The black solid, green dotted, cyan dashed, magenta dashed-dotted, and blue dashed-dot-dotted lines represent the Salpeter, mass-heavy, top-heavy, Larson 1 and Larson 2 IMF, respectively.
