A 2909 There are many negative observations. Needs speckle.
HIP 15868. A is the close pair A 2909, 0.1". The 2MASS PSC companion
at 17" is called C in the WDS. Tok2011a
AB: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 0.62 +/- 0.11, 2.10, and 1.01 Msun, respectively. Mlk2012
CfA: SB? P=9115d? =25y? UR at SOAR from 2008.6 to 2012.9, in Mlr1955a
contradiction with orbit of Muller (1955). Tok2014d
A spurious orbit of this ghost pair has been computed which is Doc2016d
contradicted by the many non-resolutions. Tok2019d
