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. |

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. |
