Chi Aquilae


Chi Aquilae (χ Aql, χ Aquilae) is the Bayer designation for a binary star〔 in the equatorial constellation of Aquila, the eagle. This system is bright enough to be seen with the naked eye at a combined visual magnitude of +5.29.〔 Based upon parallax measurements made during the Hipparcos mission, Chi Aquilae is at a distance of approximately from Earth.〔
The brighter member of Chi Aquilae is yellow-hued G-type star with a stellar classification of G2 Ib-II and an apparent magnitude of 5.80. A luminosity class of Ib-II indicates the spectrum lies midway between that of a bright giant and a supergiant star. The companion is a white-hued A-type main sequence star with a classification of B5 V and an apparent magnitude of 6.68.〔 As of 2004, the secondary is located at an angular separation of 0.418 arcseconds along a position angle of 76.7° from the primary.〔
