Table 2
Parameters used to determine the similarity criterion given by Eqs. (11)–(13) that shows how similar a synthetic system is to the observed Trappist-1 planetary system.
| Parameter | Trappist-1 |
|---|---|
| Mean mass | 0.8079 M⊕ |
| Variance mass | 0.362 M⊕ |
| Total mass | 5.655 M⊕ |
| Mean period ratio | 1.5226 |
| Variance period ratio | 0.1117 |
| Mean eccentricity | 0.0063 |
| Variance eccentricity | 0.0025 |
| dMp∕dP | −0.0206 M⊕∕d |
| σ(Mp − Mcp) | 0.3393 M⊕ |
Notes. The values for Trappist-1 are taken from Grimm et al. (2018).
