GHE 34 | The primary is Sz 22, embedded in a circumstellar disk or reflection | |
nebula. Schmidt et al. (2014) resolve the A component into a 0.5" | ||
pair; the Ab component is a co-moving M4.5 +/- 1.5 dwarf. | Sdt2013 | |
LAF 8 | BC: Daemen et al. (2013) derive the following component properties | |
(units are K,Lsun,Myr,Msun,Rsun): | ||
B: SpT = M0.5 Teff = 3780 +- 400 L = 0.50 +- 0.09 | ||
Age = 2.0 +8/-1.1 M = 0.52 +0.38/-0.19 R = 0.47 +- 0.05 | ||
C: SpT = M0.5 Teff = 3780 +- 400 L = 0.090 +- 0.006 | ||
Age > 23. M = 0.50 +- 0.2 R = 0.70 +- 0.07 | Dae2013 |
