Comparison of radiative transfer models for the disk of 01-580, the only accreting star in NGC 7160. Blue dots mark the data (errors are often smaller than the dots). Inverted triangles are upper limits. The dashed line is a MARCS photospheric model (Gustafsson et al. 2008). The colour lines show models with different vertical structures (flaring laws H/R, outer disk thickness), grain size distributions, and disk masses. The model labelled “Mixed” includes well-mixed dust and gas. Even if the disk is assumed to be very settled, substantial mass depletion is required to fit the 160 μm upper limit.
