…that PDS 70 c completes nearly one revolution once every time PDS 70 b completes nearly two. Modelling predicts that PDS 70 b has acquired its own circumplanetary disk (CPD). The CPD was at first observationally supported in 2019, however, in 2020 evidence was presented that the current data favor a model with a single…
