Basic properties of our 3D simulations.
| Model name | t45g46m00 | solar | t62g43m00 |
|---|---|---|---|
| Teff(K) | 4571 ± 7 | 5772 ± 16 | 6231 ± 14 |
| log g(cgs) | 4.62 | 4.438 | 4.319 |
| dgran(Mm) | 0.78 | 1.51 | 3.17 |
| v̂h(km/s) | 1.58 | 2.32 | 3.01 |
| tgran(s) | 248 | 326 | 527 |
Notes. t45g46m00 is set up to replicate ε Indi A and t62g43m00 corresponds to an F-type MS star. As Teff is an emergent quantity of the 3D simulation that fluctuates with time, both its time-averaged mean and standard deviation are given. Symbols dgran and v̂h denote typical granule size and representative value of horizontal velocity at the stellar surface, respectively. The granulation timescale is estimated through tgran=dgran /(2 v̂h).
