Theoretical modeling of Spectral Energy Distributions (SEDs) has proved an invaluable tool for understanding the structure and properties of protoplanetary disks. However, SEDs building requires accessing to a variety of astronomical services providing, in most of the cases, heterogeneous information. Moreover, model fitting demands a tremendous amount of work and time which makes it very inefficient even for modest datasets.
In the framework of the Spanish Virtual Observatory we have developed VOSED (http://sdc.laeff.inta.es/vosed), a tool that permits to characterize the protoplanetary disks around young stars taking advantage of VO standards and tools. The application allows the user to gather photometric and spectroscopic information, trace the SED, and fit the photospheric and disk contributions following a Bayesian approach.
In this paper the functionalities of VOSED are presented.
