discov_num notes refcode
REP 17 DI Cha, a quadruple in a star-forming region in Chamaelon. Schmidt et
al. (2013) resolve the primary into a 0.2" G2/M6 pair, with estimated
orbital period of 130y. The B component is a 50mas pair of M5.5 +/-
1.5 dwarfs, with estimated period 65y. Sdt2013
Daemen et al derive component properties (units K,Lsun,Myr,Msun,Rsun):
A: SpT = G0 Teff = 6030 +- 290 L = 4.7 +- 1.0
Age = 7.1 +3.0/-0.7 M = 1.7 +- 0.2 R = 2.00 +- 0.10
B: SpT = M5 Teff = 3130 +- 290 L = 0.11 +- 0.02
Age = 3.0 +3.0/-2.8 M = 0.18 +0.06/-0.08 R = 1.13 +- 0.11 Dae2013
