discov_num notes refcode
BUG 3 Liu et al (2008) estimate spectral types T5.0 +/- 0.5 and T5.5 +/- 0.5 LiM2008
and effective temperatures 1028 +/- 17 and 978 +/- 17K. Orbital
elements, determined using a Markov Monte Carlo technique, yield
masses 0.0287 +/- 0.0016 and 0.0269 +/- 0.0016 Msun. Age of the system
is estimated at 0.78 +/- 0.09 Gyr.
Assuming a parallactic distance of 13.59 +/- 0.22 pc
(Tinney et al. 2003), Konopacky et al. (2010) derive a system mass of Bug2003b
0.060 +/- 0.004 Msun. Kon2010
