THA 1 Primary is Gl 758, a high-metallicity G9 dwarf atdistance of 15.5pc.
The faint B component is found to share common proper motion. Mass of
B is estimated to fall in range 10.3-34.3 Mjup, temperature 549-637K;
spectral type T9. C component is considered candidate companion. Tha2009
Based on additional epoch astrometry, the C component appears to be a
background star. Jnn2011
AB: Nilsson et al. (2017) derive a spectral type for the secondary of
T7.0 +/- 1. Teff = 741 +/- 25K; inferred mass is 40-50 Mjup. Nln2017
