discov_num notes refcode
NHR 8 GQ Lup
Primary is L1, age < 2 Myr. Radius of secondary may be ~2 Rjup and
mass a few Jupiters. Nhr2005
Mugrauer & Neuhauser (2005) reanalyze all relative astrometry and Mug2005b
conclude that pair is CPM and likely bound.
Guenther et al. (2005) determine spectral type of secondary M9V - L4V, Gue2005
Teff 1600-2500K.
Aa,Ab: Primary is T-Tauri type variable GQ Lup. Kraus et al. (2014)
estimate the mass of the companion at 31 +/- 3 Mjup. KsA2014
