STF1619 AB: NLTT 30106/30107 Chm2004
C is BD-06@3533.
A rectilinear solution to AB gives a poor fit, due to slight apparent
curvature suggesting very long-period orbital motion.
AB: The AB pair is comprised of a K0V and a K1V star, at a distance of
35.19 +/- 0.74pc. The C component is not a physical companion. Rica et
al. (2017) derive a combined spectroscopic/astrometric orbit of AB,
finding a period of 4800 years and a separation of 345au. The orbit is
perturbed by a circumprimary planet of mass 9.6 Mjup, previously
discovered through radial velocity variations (Mayor et al., 2011 A&A
submitted, arXiv:1109.2497M) FMR2017
