A premature orbit has been computed. |

A family of possible orbital solutions are determined by Romanenko |

(1994), with periods ranging from 5,200 to 120,000 years, using the |
|
|
method of apparent motion parameters and incorporating parallax and |
|
|
radial velocity information. |

31 Dra. Toyota et al. (2009) monitored the RV of both the A and B |
|
|
components every 1-2 months between 2003 Mar - 2007 Nov, using a |
|
|
high-dispersion echelle (precision ~10 m/s). The A component exhibits |
|
|
a linear trend in RV, with a slope +220 m/s/y. Toyota et al. assert |
|
|
that these variations are due to an unseen companion. Assuming a |
|
|
circular orbit, period is estimated at 3200d; minimum mass of the |
|
|
unseen star ~50 Mjup. Standard deviation of radial velocities for the |
|
|
B component <40 m/s and velocities show no periodic variation. This |
|
|
result rejects the association of a planet of mass > 1.8 Mjup |
