The protoplanetary disk around the T Tauri star PDS 70 is of particular interest as it exhibits multiple elements predicted by the theory of planet formation. This disk displays: a variety of axisymmetric substructures observed in both the continuum and line emission; two planets embedded in a dust-depleted gap; and at least one circumplanetary disk. These characteristics motivate the development of detailed thermo-chemical models to interpret different observations from PDS 70.

In this talk, I will present our efforts to construct a two-dimensional thermo-chemical model aimed at reproducing simultaneously different observables from the PDS 70 disk across a wide range of wavelengths. I will present two applications of our model: estimating the mass for the embedded planets based on ALMA data and providing a preliminary characterisation of the volatile content in the inner disk based on JWST observations.

Overall, our results show that the level of gas depletion in the disk’s gap is consistent with constraints on planet masses derived from infrared observations. For the inner disk, the ratio of the elemental abundance of carbon to oxygen is below one.

I will conclude my talk introducing the context and outlining the goals of my project at Penn State.
