  In our ongoing deep infrared imaging search for faint wide secondaries of
planet-candidate host stars we have confirmed astrometrically the companionship
of a low-mass object to be co-moving with HD89744, a companion-candidate
suggested already by Wilson et al. (2000). The derivation of the common proper
motion of HD89744 and its companion, which are separated by 62.996+-0.035
arcsec, is based on about 5 year epoch difference between 2MASS and our own
UKIRT/UFTI images. The companion effective temperature is about 2200 K and its
mass is in the range between 0.072 and 0.081 Msun, depending on the
evolutionary model. Therefore, HD89744B is either a very low mass stellar or a
heavy brown dwarf companion.
