Spectral type M8Vp or M8βγ (Cooper et al. 2024). Age 10-40 Myr. Possible substellar exoplanet host. Filippazzo et al. (2015) calculate a mass within the range of brown dwarfs (m = 39.0 ± 23.17 M_Jup), whereas TESS provides a mass estimate more compatible with a low-mass star (m = 0.1143 ± 0.02 M_Sol).
A transiting companion larger than Jupiter (r = 1.36 R_Jup) with ultra-short orbital period (P = 0.337 d) is reported, unless the transit is actually a blend due to a background eclipsing binary.
