[2] The binary nature of this system was announced in 1980 by Erika Böhm-Vitense based on an ultraviolet excess attributed to a white dwarf companion.

[8] It was flagged as a suspected eclipsing binary in 1988 due to observed variations in the light curve.

The properties of these objects include overabundances of carbon molecules (such as C2) and s-process elements.

[4] It is about as massive as the Sun, and its temperature is 23,000 K. In the course of its evolution, the progenitor star passed through the thermally pulsing asymptotic giant branch, during which the enlarged atmosphere transferred material to the primary.

[20] Consequently, the Chinese name for ζ Capricorni itself represents the state of Yan (燕),[21] together with ν Ophiuchi in Left Wall of Heavenly Market Enclosure (asterism).
