Alpha Pavonis (α Pavonis, abbreviated Alpha Pav, α Pav), formally named Peacock /ˈpiːkɒk/, is a binary star in the southern constellation of Pavo, near the border with the constellation Telescopium.

Of the fifty-seven stars included in the new almanac, two had no classical names: Alpha Pavonis and Epsilon Carinae.

Alpha Pavonis was named "Peacock" ('pavo' is Latin for 'peacock') whilst Epsilon Carinae was called "Avior".

Consequently, α Pavonis itself is known as 孔雀十一 (Kǒng Qiāo shíyī, English: the Eleventh Star of Peacock.

Hence the material found in the outer atmosphere is not processed by the nuclear fusion occurring at the core.

[19] α Pavonis A is a spectroscopic binary consisting of a pair of stars that orbit around each other with a period of 11.753 days.
