Multi-technique observations and modeling ofprotoplanetary disks

摘要

Most of the studies on circumstellar disks are based on models that put an emphasis onfitting either SEDs or scattered light images or molecular emission maps. In this contribution, wepresent a more general approach which aims at interpreting the increasing amount of observationaldata in the framework of a single model, in order to obtain a more global picture and to bettercharacterize both the dust population and the gas disk properties. The main objective of this generalmethod is to couple the constraints from the gas- and dust-oriented studies to shed light on aspectsof the disk structure that are cannot otherwise be studied in a coherent manner.
