Description
The large variety of observed planetary systems is rooted in the complex physical and chemical processes that lead to their formation. In the last few years, great observational and theoretical developments have dramatically improved our understanding of how forming planets are affected by and interact with their birth environments, the protoplanetary disks. As host to two accreting planets, PDS 70 provides a unique opportunity to probe how planets sculpt their hosting protoplanetary disk in its density and kinematical structure, to characterize the chemical complexity of atmosphere-forming material, and to directly observe the moon-forming potential of their circumplanetary disks. In this talk, I will present recent and new data of the PDS 70 system, showing new evidence of circumplanetary disks, of high C/O ratio gas in the proximity of the two planets, and new evidence of the mutual interactions between the accreting planets and their hosting disk.
