Stellar parameters for the Capella primary.
| Parameter | Primary | Secondary | MGS | Ref. |
|---|---|---|---|---|
| Teff (K) | 4943 ± 23 | 5694 ± 73 | 100 | Takeda |
| log g (cgs) | 2.52 ± 0.08 | 2.88 ± 0.17 | 0.5 | Takeda |
| [Fe/H] | 0.10 ± 0.05 | −0.08 ± 0.08 | var | Takeda |
| ξt (km s−1) | 1.47 ± 0.13 | 2.29 ± 0.38 | 2.0 | Takeda |
| ζ (km s−1) | 6.6 ± 0.4 | (7.0)* | ... | Torres |
| vsini (km s−1) | 4.1 ± 0.5 | 35.0 ± 0.5 | ... | Torres |
Notes. MGS: model-grid-step size of the used MARCS models. The microturbulence, ξt is fixed in the models. The metallicity, [Fe/H], has been varied. *The macroturbulent velocity for the secondary was set to 7.0 km s−1.
