| Method | M⋆ (M⊙) | R⋆ (R⊙) | ρ⋆ (g cm−3) |
|---|---|---|---|
| ARIADNEa | 0.876 ± 0.038 | 0.820 ± 0.017 | 2.2 ± 0.2 |
| Torres | 0.900 ± 0.060 | 0.872 ± 0.061 | 1.9 ± 0.4 |
| PARAM 1.3b | 0.867 ± 0.027 | 0.822 ± 0.018 | 2.2 ± 0.2 |
| K0Vc | 0.88 | 0.81 | 2.3 |
Notes. (α)ARIADNE (Vines & Jenkins 2022) computes the stellar parameters from a combination of the SED fitting and MIST isochrones (Choi et al. 2016). Adopted as the final parameters for the modelling in Sect. 3.4. (b)da Silva et al. (2006). (c)https://www.pas.rochester.edu/~emamajek/EEM_dwarf_UBVIJHK_colors_Teff.txt.
