SED model of GSS30-IRS1 considering dust-only emission (black solid line), compared to observed flux densities from this work (closed circles) and the literature (open circles). Derived parameters are annotated in the bottom right, alongside the 16th and 84th percentile uncertainties, in addition to 1000 draws from the posterior as the orange shaded region. Note that even with extreme dust disk properties, the model cannot replicate the radio SED at frequencies ≲40 GHz.
