| Teff (kK) | 93.5 | ±1.5(a) | 3.6 | ±0.2 |
| Albedo | 1.0 (fixed) | 1.0 | ±0.01 | |
| Linear LD coeff. | 0.03 | ±0.03 | Interpolated(b) | |
| Orbital period (days) | 0.245845 | ±0.000003 | ||
| Orbital inclination | 80.65° | ±0.1° | ||
Notes.
Based on the implied luminosity, the uncertainty on the primary temperature is likely underestimated. See text for discussion.
Interpolated limb darkening, based on the Castelli et al. (2003) atmospheres as implemented in PHOEBE2 (Prša et al. 2016), was used rather than a linear limb-darkening law.
