| ROSAT X-ray luminosity (ergs s−1) | 3.62 × 1027 | Callingham et al. (2021b) |
| Hα equivalent width (Å) | 6.85 ± 0.09 | Newton et al. (2017) |
| Surface polar magnetic field ( * ) (kG) | 4.53 | Morin et al. (2010) |
| Stellar rotation period (days) | 0.78 | Morin et al. (2010) |

Notes. ( * )Morin et al. (2010) also found that the magnetic field is well described by a dipole: 
, where B0 is the polar surface field strength, R is the radial distance in units of the stellar radius, θ is the polar angle, and 
and 
are the unit vectors along the radial and polar-angular directions.
