Ankaa
(AN-kuh)
Alpha Phoenicis
Names For This Star
Other names for this star are Nair al Zaurak, Cymbae, Lucida Cymbae, and the Head of Phoenix.
Na'ir al Zaurak is Arabic and means "The Bright One in the Boat." Lucida Cymbae is a Latin translation of this name, from which comes the abbreviated name "Cymbae."
Thus far I have been unable to discover the origin of the name Ankaa by which this star is most widely known.
Description of the Star
Ankaa is an orange K0III normal giant. The spectral type implies an effective temperature of 4500 K, a diameter 16 times that of the sun, and a mass about four times that of the sun. The luminosity of the star would be about 80 times that of the sun.
Ankaa has a companion that orbits with a 10.5 year period. The separation of the companion from the primary is at least 1.7 AU. This is slightly larger than the separation of Mars from the sun.
