Table 1
General characteristics of the planets in the HZ for simulations S1, S2, and S3 for γ = 0.5.
| Simulation | ai (AU) | af (AU) | M (M⊕) | W (%) | TLGI (Myr) | ||

| S1 | 0.95 | 0.94 | 0.1 | 4.44 | 146 | ||
| S2 | 1.28 | 1.36 | 0.1 | 0.06 | 49 | ||
| S3 | 1.20 | 1.15 | 0.03 | 5.37 | – | ||
Notes. ai and af are the initial and the final semimayor-axis of the resulting planet in AU, M is the final mass in M⊕, W is the percentage of water by mass after 250 Myr, and TLGI the timescale in Myr of the last giant impact. The planet in the HZ of S3 has not yet experienced a giant impact; it has only acreted planetesimals. As we mentioned in Sect. 4.1, this planet could collide with the third planet of the system if we had extended the simulations beyond 250 Myr.
