For those who don&#x27;t know, only PDS 70b and c are the exoplanets directly imaged which are still embedded inside thier nascent protoplanetary disk. For most other planets, the disk gas has mostly been cleared/dissipated/accreted. For those who are more interested you can refer to the detection papers for both: PDS 70b: https://www.aanda.org/articles/aa/pdf/2018/09/aa32957-18.pdf PDS 70c: https://www.nature.com/articles/s41550-019-0780-5 Arxiv link for Nature paywall (PDS 70c): https://arxiv.org/abs/1906.01486</p><p><a href="https://hackerpaper.kaipfister.de/p/1906.01486/">Paper and discussion history</a>.
