discov_num notes refcode
SDT 1 AB: Companion appears to be co-moving with primary CT Cha. Schmidt et
al. (2008) estimate the spectral type of the secondary at M8-L0.; most Sdt2008b
probable mass is 17 +/- 6 Mjup. C component is a background star.
Daemen et al derive component properties (units K,Lsun,Myr,Msun,Rsun):
A: SpT = K7 Teff = 4060 +- 180 L = 0.67 +- 0.15
Age = 3.0 +3.0/-1.5 M = 0.78 +- 0.20 R = 1.66 +- 0.07 Dae2013
