Notes

Suspected by Vaidis (1988). Previously classified as Mep? by Sanduleak & Stephenson (1973), and as a probable T Tauri star by Henize (1976). Weak TiO absorption, along with Balmer lines in emission, was detected by Allen (1978). Additionally, He I lines in emission were observed by Schwartz & Noah (1978). In Pereira et al. (2003), it was noted that the continuum spectrum resembles that of known T Tau stars, with the detection of He II in emission. Dwarf classification is further supported by the Gaia distance.
