discov_num notes refcode
RST1877 Carmona et al. (2007) reanalyzed the data obtained by Perez et al. Crm2007
(2004), resulting in a change in his position angle from 353 to 4deg. Pez2004
Muller et al. (2011) resolved the B component into a close pair, which MuA2011
they referred to as BC. However, the C component is a long-known
distant member of the system, so the close pair has been renamed Glp1892f
MUA 1 Ba,Bb. They derive the following parameters for the close
members of the system:
component: A Ba Bb
spec: F0IIIe K7V M1V
L (Lsun) 12.7 +6.4/-3.7 0.50 +0.24/-0.20 0.41 +0.19/-0.16
Teff (K) 7220 +/- 115 4000 +/- 250 3750 +/- 250
M (Msun) 1.8 +0.2/-0.1 0.8 +/- 0.2 0.5 +/- 0.2
R (Rsun) 2.3 +/- 0.5 1.5 +/- 0.7 1.5 +/- 0.7
