HR 1884

HR 1884 is a spectroscopic binary star in the constellation Auriga. The primary is a G type supergiant star while the secondary is probably a B type main sequence star.

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. In the same year, William P. Bidelman noted that the stellar spectrum was composite indicating a companion star. Confirmation of spectroscopic binary status and a preliminary orbit was published in 1998 by R. Paul Butler, a much more accurate orbit was published in 2015 by Roger Griffin.
