discov_num notes refcode
KOI3158 A,BC: Kepler-444 is a metal-poor triple system that hosts five
sub-Earth-sized planets. The secondary is an SB2 consisting of two M
dwarfs. Dupuy et al. (2016) determine an eccentric orbit of A,BC and
derive mass ratios (M_B + M_C)/M_A = 0.71 and M_C/M_B = 0.86 +/- 0.03.
Limits are determined for the BC orbit, with a <10mas. System mass is
1.30 +/- 0.06 Msun. Dup2016b
