Alternate Names

HIP 81208 B

Companion star to HIP 81208 is labelled by discoverers as "C" with inner brown dwarf companion to primary star labelled as "B". If the latter is regarded as "HIP 81208 Ab", the companion star becomes "B". Moreover an additional common proper motion M dwarf companion star (2MASS J16360769-3543514) lies 148.7 arcseconds away (97,580 AUs at 148.7 pc) and this one should be hence regarded either as "HIP 81208 C" or "D".
