Notes

Listed among possible symbiotic stars in Vaidis (1988), likely due to the reported spectral type Mep + B by Sanduleak & Stephenson (1973) and its inclusion in the catalog of Allen & Glass (1974). Although initially considered a possible PN in Henize (1967), this classification was refuted by Acker et al. (1987) and Stenholm & Acker (1987). The object was subsequently reclassified as an M-type emission line star in Kohoutek (2001). A spectrum presented in Pereira et al. (2003) displayed several hydrogen and helium absorption lines, leading to its categorization as a reddened Be star.
