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. |
