Simulations of the Solar System with captured and scattered asteroids in the Galactic potential.
| Scattered and captured asteroids (see Sect. 3.2) | |
|---|---|
| Designation | Simulation A |
| Simulations | Two simulations of the Solar System with planets, and scattered and captured asteroids in the Milky way potential. |
| Star | Single 1 M⊙ star in the smooth potential of the Milky Way galaxy. |
| Planets | Four planets per star in a circular disk, with Jupiter, Saturn, Uranus, and Neptune in circular orbits with semi-major axes of 5.1, 9.5, 19.2, and 30.1 au, respectively. |
| Asteroids | One simulation with 2000 asteroids (from planetary system # 157 of Sect. 3.3.2; see also Torres et al. 2020a). One simulation with 1888 asteroids (from the most probable encounter, which, according to Jílková et al. (2015), resulted in a population of Sedna-like objects). |
| Numerics | Huayno (Pelupessy et al. 2012) coupled with the Galactic model (see Table 5) via bridge (Portegies Zwart et al. 2020) in AMUSE (Portegies Zwart & McMillan 2018). |
| Computer | Run on Cartesius, and ALICE using GPU. |
| Duration | The simulations started at an age of ~100 Myr. By that time, the Solar System has left the parent cluster, and continues for 1 Gyr. |
