SPF 2 | Stumpf et al. (2011) estimate the period at 21 +/- 1 yr and the system | Spf2011 |
mass at > 78 Mjup. Near-IR colors suggest spectral types T1 +1/-4 and | ||
T2.5 +/- 1. | ||
SDSS J205235.31-160929.8. Bardalez Gagliuffi et al. (2015) derive a | ||
preliminary orbit for this very low-mass binary, deriving a system | ||
mass of 0.0823 +0.0037/-0.0027 Msun and spectral types L6.0 +/- 2.0 | ||
and T2.0 +/- 0.05. (Note: the quoted 2453654.31 Julian date for tau_0 | ||
does not appear to correspond to the best-fit T0. To was adjusted to | ||
2455054.31 for the orbit catalog figure.) | BGg2015 |
