WebAug 16, 2024 · PDS70 is a unique system in which two protoplanets, PDS70b and c, have been discovered within the dust-depleted cavity of their disk, at 22 and 34au respectively, by direct imaging at infrared wavelengths. Subsequent detection of the planets in the H line indicates that they are still accreting material through circumplanetary disks.
