Notes. SB: spectroscopic binaries, AB: astrometric binaries (with orbital solution), AA: stars with astrometric acceleration, VB: visual binaries, EB: eclipsing binaries, Ba: barium stars (abundance anomalies indicating a WD companion). In the semimajor axis column the asterisks indicate the projected separation in AU as measured from imaging observation. HIP 112504 is a triple system. The moderately wide visual companion and the close spectroscopic companion are listed as separated entries.
