Notes

Included in the list of late-type emission-line stars by Allen (1973), these stars were identified as potentially either symbiotic stars or heavily reddened objects. The paper also mentioned that the infrared continuum is dominated by the late-type companion. The star was classified as a Be star in Merrill et al. (1925), a P Cygni-type star in Struve (1944), a B3neq star in Arkhipova (1963), and a B0.5 Ia with emission lines in Vijapurkar & Drilling (1993).
