Notes

Suspected in O´Donoghue et al. (2013), based on the spectrum showing molecular bands, with the conclusion that the spectrum is similar to T CrB. The object was also included in the All-sky catalog of bright M dwarfs by Lépine & Gaidos (2011), and high proper motion and parallax from their catalog are confirmed by Gaia DR2. However, Merc et al. (2021) confirmed its non-symbiotic nature and suggested that it is either a MS-MS or MS-WD binary.
