The primary is a G type supergiant star while the secondary is probably a B type main sequence star.[5] The possible spectroscopic binary nature of the star was first noted in 1983 by Gilbert Burki and Michel Mayor in a paper on the rate of binaries among supergiant stars.[20] In the same year William P. Bidelman noted that the stellar spectrum was composite indicating a companion star.[21] Confirmation of spectroscopic binary status and a preliminary orbit was published in 1998 by R. Paul Butler,[22] a much more accurate orbit was published in 2015 by Roger Griffin.[5] References1. ^1 {{cite journal | title=Spectral Classification of Stars Noted on Case Objective-Prism Plates.
