| Abstract: |
Most studies on circumstellar disks are based on models that
put emphasis on fitting either SEDs or scattered light images. In this
contribution, we present a more global approach which aims at
interpreting consistently the increasing amount of observational data
in the framework of a single model, in order to get a more global
picture and to better characterize both the dust population and the
disk properties. Results of such a modeling applied to a few disks (GG
Tau, IRAS 04158) for which large, multi-wavelength observational
data-sets are available (scattered light images, polarization maps, IR
spectroscopy, X-ray spectrum) are presented. In particular, we
illustrate how resolved polarimetry is a powerful tool to break
degeneracies between model parameters and obtain tight constraints on
dust properties. |
