Protoplanetary disks are accretion driven structures conformed of dust and gas that can be found around young stars. A good understanding of their properties can help predict where and what type of planets will be formed, if the system is stable against collapse... A careful modelling of dust emission using auto-consistent radiative transfer models has been performed in this work using the D'Alessio Irradiated Accretion Disks (DIAD) code, described in D'Alessio+06. This code takes into account stellar irradiation and heating by viscous dissipation which allows to infer the temperature as a function of disk radius and scale height in a self- consistent way, provided the stellar properties are known.
