BWL 25 Makarov & Kaplan (2005) and Frankoswki et al. (2007 A&A 464, 377) Mkr2005
found evidence for a close astrometric companion based on differences
between Hipparcos and Tycho-2 proper motions. Two epochs at Keck in
Mar 2011 and Feb 2013 show substantial orbital motion. The system was
unresolved by Subaru in Dec 2011, suggesting the secondary had moved
too close to the primary to be resolved. System is a probable member
of the Carina young moving group, with an age ~30 Myr. Primary is
GJ 2079 = DK Leo. Bwl2015
A is also a 73d spectroscopic binary. Tok2019b
