PDS 70 c and SR 12 c: Observational Constraints on Giant-Planet and Satellite Formation
The episode discusses a paper by I. Mosqueira analyzing PDS 70 c and SR 12 c, the only two planetary-mass objects with detected cold circumplanetary disks. The hosts explain how these observations support a model of moon formation in quiet, solids-enhanced disks, with PDS 70 c's dust mass comparable to Callisto and SR 12 c's growth essentially halted.
