STT 550 AB: Optical pair, based on study of relative motion of the components
using the method of apparent motion parameters. Kiy2008
LUH 3 54 Psc. AC: Common proper motion for both components was determined
through comparison of relative location with that obtained by 2MASS.
The B component is determined to be a possible T dwarf (T7.5 +/- 0.5)
based on mid-IR colors and magnitudes. Age is determined to be 7 +/-
3 Gyr and mass of C component 0.051 +/- 0.014 Msun. Luh2007
The T dwarf is referred to by Luhman et al. as the "B" component,
either because the non-physical STT 550 was not considered, or the WDS
was not consulted. In any event, this component referred to in the WDS
hierarchy as "C" is sometimes called "B" in the literature.
CHARA Array Limb-darkened diameter 0.790 +/- 0.027 mas, CIA2008c
R = 0.947 +/- 0.032 \rsun.
