Robitaille et al. (2006) YSO SED Models

These are models that were published in Robitaille et al. (2006).

Important

Please read this disclaimer before downloading the models!

You are responsible for reading about the models and ensuring that you understand all the limitations inherent to YSO SED models in general, and this specific set of models. A number of caveats related to the models are listed in Section 2.2.4 of Robitaille et al. (2006) and a number of more general limitations are also discussed in Robitaille (2008).

In particular, it is very important to not over-interpret results carried out by fitting these models. The models are simple axisymmetric 2-D models, which are likely only a very rough approximation of reality, and the models should only be used accordingly. The \chi^2 value is thus not meaningful in the traditional statistical sense of being linked to a well-defined probability. The models also include strong correlations between parameters due to the way the parameters were sampled (this is described in more detail in the two publications linked above) and can therefore not be reliably used to search for real trends in datasets.

An example of a study using the models in the way they were intended (as rough probes of evolutionary stage), see Forbrich et al. (2010). In addition, an example of a study of the reliability of SED modeling for protostars with these models is presented in Offner et al. (2012).

Note

the default parameters.fits file contained in the above model package does not include the envelope mass. If you are interested in this parameter, you will need to download this file, decompress it, then put it inside the models_r06 directory and make sure it is named parameters.fits.
