Density structure of inner rim and impact on SED. The upper left plot shows the prescribed density structure of our best-fitting model. Dashed contour lines in the upper panel refer to the calculated dust temperatures. The upper right plot represents a model with identical parameters where, however, the vertical disk structure is calculated consistently with the resultant gas temperatures and mean molecular weights, which results in a flatter midplane close to the star and too little near-mid IR excess (lower right plot). Note the “soft inner edge” (see Woitke et al. 2009). The lower left plot compares the prescribed scale height of the best-fitting model (full line) with the scale heights resulting from the model with calculated vertical disk stratification. The red dotted line shows these results in a deeper layer at z/r = 0.05, and the blue dotted line at z/r = 0.5.
