The effects of dust evolution on disks in the mid-IR

摘要: In this paper, we couple together the dust evolution code two-pop-py with thermochemical disk modelling ProDiMo. We create a series of models that simulate over time from 0.018 Myr to 10 Myr, including radial drift, growth, and settling grains. examine effects on mid-infrared gas emission, focussing spectral lines C2H2, CO2, HCN, NH3, OH, H2O are readily observable Spitzer upcoming E-ELT JWST. The addition acts increase line fluxes by reducing population small find all species except C2H2 respond strongly evolution, increasing more than an order magnitude across model as density grains decreases time. The extremely low due lack abundance in infrared line-emitting regions, despite being commonly detected Spitzer, suggesting warm chemistry inner may need further investigation. Finally, CO2 flux densities rapidly other evolves. This suggests ratios be lower disks less-evolved populations.
