CHR 225 It in uncertain whether the pair resolved here is the known G8III+A0V
composite spectrum binary (Hoffleit & Warren 1991). The small apparent Hof1991
change in theta over the 4-year span between observations does not
appear consistent with our estimated period of ~15 or so years;
however, the magnitude difference between the components is small, so
we are unable to rule out a 180 deg quadrant flip or perhaps an
eccentric orbit. Hrt1996b
Docobo et al. (2014) use the spectroscopic elements of Carquillat &
Prieur (2007), together with speckle data and the Hipparcos parallax, Crq2007
to derive the remaining orbital elements. The resulting masses are
1.92 +/- 0.26 and 2.50 +/- 0.29 Msun. Doc2014h
