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 |
