Its primary is a B-type main-sequence star, and the secondary an A-type main-sequence star. The secondary star may be an Am star. [4] Farther out are two other stars, designated components C and D. They are 76.1″, or about 1.27′, away from the central system. [9] Their combined spectrum matches that of another B-type main-sequence star. [6]
A multiple star system consists of two or more stars that appear from Earth to be close to one another in the sky. [dubious – discuss] This may result from the stars actually being physically close and gravitationally bound to each other, in which case it is a physical multiple star, or this closeness may be merely apparent, in which case it is an optical multiple star [a] Physical multiple ...
