Abstract
We discuss silicate emission profiles observed with the ISO SWS and gr ound-based IR observations in a population of intermittently embedded Herbig Ae/Be stars which are viewed edge-on to their polarimetrically identified dust and gas disks. The ISO SWS observations confirm the la ck of a simple correlation between system age and the profile shape. C omparison with laboratory silicates suggests that much of the observed variation is due to different annealing histories of the grains.
