Notes

The suggestion of symbiotic nature for AR Cir was initially proposed by Harrison (1992) due to the similarity in the light curve shape with other symbiotic novae, particularly very slow novae (Duerbeck (1987)). However, Duerbeck & Grebel, 1993 contradicted the symbiotic classification as they did not detect the expected M0III star spectrum suggested by Harrison (1992). Instead, they proposed that the bright component is a foreground K3V star, and the faint component corresponds to the object originally observed in a nova outburst. Thus, Duerbeck & Grebel (1993) concluded that AR Cir is a heavily reddened slow classical nova.
