Notes. The first model is shown in Fig. 10, panel C. From Teff and Lbol we calculate the stellar radius to be R = 1.93 ± 0.12 R⊙ resulting in a mean of 0.97 ± 0.06 R⊙ for each component in NY Hya. Some uncertainties are too optimistic. Models: BT-NEXTGEN-GNS93 (1,11,12,13), KURUCZ (14), BT-NEXTGEN-AGSS2009 (2,9), BT-DUSTY (3), BT-COND (4), BT-SETTL-AGSS2009 (6), BT-SETTL-CIFIST (5,7), NEXTGEN (8,10,11), and COELHO (15) with [α/Fe] = 0.4 dex. Formal weighted means for old estimates of solar abundances: Teff = 5636 ± 25 K, log g = 4.286 ± 0.081 (cgs), [m/H] = −0.167 ± 0.056 dex and for recent solar abundances: Teff = 5788 ± 18 K, log g = 4.202 ± 0.096 (cgs), [m/H] = 0.0 ± 0.0 dex. For a reference to each model, see text for details.
