Gl 86. Magnitudes are K magnitudes of Lagrange et al. (2006). |
|
|
Lagrange et al. (2006) give two possible orbital solutions, based on |
Lgr2006 |
|
different assumed masses (70 Mjup and 0.5 Msun) for the secondary. |
|
|
Semi-major axes converted from au (47.58 and 18.42 au, respectively) |
|
|
to arcseconds assuming an Hipparcos-based distance of 10.9 pc. |
|
|
JHK photometry of primary from 2MASS, that of secondary transformed |
|
|
from NACO to 2MASS filters. |
|
|
2001.7454: PA is measured in zenith mode. If data collected in |
|
|
equatorial mode, PA = 112.1. |
Rbr2011d |
|
Farihi et al. (2013) derive a mass of 0.59 +/- 0.01 Msun and |
|
|
Teff = 8180 +/- 120K for the white dwarf companion to GJ 86. Monte |
|
|
Carlo simulations yield the following orbital constraints: |
|
|
P = 120-481y, T0 = 1933-2067, e = 0.00-0.61, i = 114.7-122.6deg, |
|
|
a = 2.57-6.47" (27.8-69.8 au) Omega = 63.7-76.1deg, omega=0-358deg. |
|
|
The upper ranges of P and a are considered less likely. |

A: Combined solution, based on reduction of Hipparcos intermediate |

astrometric data together with spectroscopic elements from Queloz |
