Table 1
Values of the parameters describing the planetary system of Alpha Centauri A used in our numerical modeling.
| Parameter (unit) | Symbol | Value |
|---|---|---|
| Stellar radius (RSun) | Rs | 1.2234 |
| Stellar effective temperature (K) | Ts | 5790 |
| Planet radius (km) | rp | 6052 |
| Planet orbital distance (AU) | d | 0.86 |
| Planet orbital period (yr) | P | 0.76 |
| Distance to the system (ly) | D | 4.2 |
| Angular separation (arcsec) | S | 0.67 |
Notes. The orbital distance d of the planet has been chosen such that it receives the same stellar flux as Venus receives from the Sun, and in accordance with the orbit stability requirements for a planet around Alpha Centauri A predicted by Quarles & Lissauer (2016). For the radius of the Sun, RSun, we use 695 700 km.
