LUH 4 GJ 9751 = HN Peg
CHARA Array Limb-darkened diameter of A : CIA2013c
R = 1.0189 +/- 0.0291 \rsun, L = 1.0992 +/-0.0190 \lsun,
Teff = 5860 +/- 83 K, M = 0.975 \msun, Age = 5.8 Gyr.
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 (T2.5 +/- 0.5) based
on mid-IR colors and magnitudes. Age is determined as 0.3 +/- 0.2 Gyr
and mass of secondary 0.021 +/- 0.009 Msun. Luh2007
