An updated modular set of synthetic spectral energy distributions for young stellar objects

These are the models released with the following publication:

An updated modular set of synthetic spectral energy distributions for young stellar objects (Richardson et al. 2024).

This is a set of young stellar object (YSO) models with associated spectral energy distributions (SEDs) calculated through radiative transfer. It is a significant update to the data published alongside Robitaille (2017, R17). It contains the parameters shaping each model and adds the newly calculated parameters of envelope mass, average dust temperature, disk stability, and line-of-sight extinction. It also makes explicit quantities, such as source luminosity, that were left implicit in the previous release. This set also convolves the SEDs with several new filters, primarily those on the James Webb Space Telescope, and adds a script to facilitate convolution of these models with additional filters as desired by users. All data included in Version 1.1 of the R17 set (the most recent) are included here.

Like their predecessors, these models are versioned. Updates will be released as more models are completed or other changes are made.

Files unzip to r+24_models-{version}/{geometry}. "files.tar.gz" contains scripts for SED convolution and main sequence comparison, the opacity to absorption of dust used in the radiative transfer calculations, main sequence T/L values used for results in the accompanying work, and reference material for the contents of the dataset and latest version.

The primary use of these models is as templates for SED fitting. The R17 models were structured for use with the sedfitter python package, which enables fitting and analysis of the fit results. For a version of sedfitter which accommodates the new additions, use this fork.
