Structure of the PDS 70 planetary system.
| Object | Mass (MJup) | Separation (au) | Period (yr) | Pobj/PPDS 70 b |
|---|---|---|---|---|
| Inner disk | // | 9.1 | 31.5 | 0.26 |
| PLF | 0.05–0.28 |  |
 |
0.46 |
| PDS 70 b | 5.0–9.0 |  |
 |
1.00 |
| PDS 70 c | 4.4 ± 1.1 |  |
 |
1.55 |
| Outer disk (ring 1) | // | 60.0 | 533.1 | 4.32 |
| Outer disk (ring 2) | // | 74.0 | 730.2 | 5.91 |
Notes. In the second column we list the masses of the companions including that of the PLF as it was a point source. In the third column we list the separations for the companions and the inner and outer disk. In the fourth column we list the most probable periods (for the disk part we assume a Keplerian motion). Finally, in the fifth c-olumn we list the ratio between the period of the companion or disk and the period of PDS 70 b to evidence possible orbital resonance.
