Regarding the mass of component B
[edit]Is that a brown dwarf or a sub-brown dwarf since it's lower than 13 Jupiter masses? --Artman40 (talk) 15:24, 20 April 2013 (UTC)
- 6–9 MJup is below the brown-dwarf threshold, so it isn't a brown dwarf. Given the system's configuration (separation of about 2500 AU), it isn't really a planet either. It still is a planemo (planetary-mass object). Sub-brown dwarf as a more specific term seems appropriate. --JorisvS (talk) 16:37, 20 April 2013 (UTC)
