Stellar atmospheric parameters determined from spectroscopy, with and without a surface gravity constraint from asteroseismology.
Method | log g free | log g fixed |
---|---|---|
Teff (K) | 4940 ± 18 | 4950 ± 22 |
log g (dex) | 2.72 ± 0.07 | 2.67 |
vmic (km s−1) | 1.30 ± 0.06 | 1.32 ± 0.06 |
[Fe/H] (dex) | 0.16 ± 0.01 | 0.15 ± 0.02 |
Notes. The uncertainties are internal only, however systematic errors of the order of 100 K on Teff, 0.1 dex on [Fe/H] and 0.1–0.2 dex on log g are expected; this is discussed in detail in Slumstrup et al. (2019).
