Target quantities.
| Observed parameter | Description | Value | Uncertainty | References |
|---|---|---|---|---|
| (Z/X)surf | Abundance ratio of metals to hydrogen (a) | 0.0181 | 10−3 | 1 |
| 0.02292 | 10−3 | 2 | ||
| Ysurf | Surface helium abundance | 0.2485 | 0.0035 | 3 |
| RCZ | Location of the convective–radiative boundary [R⊙] | 0.713 | 0.01 (b) | |
| rms(δcs) | Root-mean-square sound speed | 0 | 10−3(c) | |
| log L⋆ | Bolometric luminosity [L⊙] | 0 | 0.01 dex (c) | |
| Teff | Effective temperature [K] | 5777 | 10 (c) |
Notes. In this work, L⊙ = 3.8418 × 1033 erg s−1 and R⊙ = 6.9598 × 1010 cm (Bahcall et al. 2005).
The (Z/X)surf value depends on the adopted abundance tables (see Sect. 3.1.4).
Bahcall et al. (2005) suggested 0.713 ± 0.001 R⊙; however, we used a larger value for convergence purposes (see text for details).
