WDS 11075-7651 REP 19 Aa,Ab : NOTES
 
 
discov_num notes refcode
REP 19 Aa,Ab: VV Cha. Imprecise coordinates led to REP 19 and KSA 42 being
Daemen et al derive component properties (units K,Lsun,Myr,Msun,Rsun):
Aa: SpT = M1.5 Teff = 3630 +- 180 L = 0.14 +- 0.03
Age = 7.0 +9.0/-3.0 M = 0.40 +0.14/-0.06 R = 0.96 +- 0.05
Ab: SpT = M3 +- 1 Teff = 3420 +- 150 L = 0.09 +- 0.02
Age = 6.4 +4.7/-2.2 M = 0.29 +- 0.07 R = 0.87 +- 0.04 Dae2013
KSA 42 initially catalogued as separate pairs. Although REP 19 was added to
the WDS before KSA 42, its WDS designation was less accurate, so was
changed from 11072-7651.
