Table 4
Number of close encounters with a 1 M⊙ star raising the planet periastron above a given value (2, 50 or 150 au) depending on the trajectory of the planet before the fly-by.
| Periastron superior to | 2 au | 50 au | 150 au |
|
|
|||
| Unstable elliptic trajectory | 8 × 10-4 | 5 × 10-5 | 2 × 10-5 |
| Slow hyperbolic trajectory | 1 × 10-4 | 2 × 10-5 | 6 × 10-6 |
| Fast hyperbolic trajectory | <1 × 10-6 | <1 × 10-6 | <1 × 10-6 |
