Abstract: We describe a model of passive circumstellar disks with inner holes and compare the SEDs predicted by this model with observations of isolated Herbig Ae/Be stars. The model can reproduce most properties of the observed stars. The near-IR emission is understood as emission from a puffed-up inner rim of the disk. The mid-IR rising SEDs of the group I sources can be fitted with large flaring disks. The mid-IR falling SEDs of group II sources is matched with small optically thick disks. The absence of the silicate emission feature at 10 μm in some group I stars cannot fully be explained as a geometrical effect.
