Past calculations of orbital elements and system mass ratios based on astrometry — and other visual observations — and the spectral
type of Star Ba (G0 - 5) indicate that Xi Ursae Majoris Bb is not massive enough to fully account for subsystem B (e.g., Wulff Dieter Heintz, 1996, page 411), and suggest the existence of a stellar companion (i.e., Bc).
