Depletion time versus dust temperature, using T_dust fitted values to obtain M_dust. Dust tmeperature is obtained from the SED model fit. The solid line represents the linear fit for the (U)LIRGs, yielding log(t_dep)=(−5.5 ± 1.0)×10⁻² T_dust + (10.1 ± 0.3). The dash lines represent the best fit considering also our local comparison sample; the fit yields log(t_dep)=(−6.9 ± 0.8)×10⁻² T_dust + (10.6 ± 0.2),
