We present the direct imaging discovery of an extrasolar planet , or possible low-mass brown dwarf , at a projected separation of 55 \pm 2 AU ( 1 \farcs 058 \pm 0 \farcs 007 ) from the B9-type star \kappa And . The planet was detected with Subaru/HiCIAO during the SEEDS survey , and confirmed as a bound companion via common proper motion measurements . Observed near-infrared magnitudes of J = 16.3 \pm 0.3 , H = 15.2 \pm 0.2 , K _ { \mathrm { s } } = 14.6 \pm 0.4 , and L ^ { \prime } = 13.12 \pm 0.09 indicate a temperature of \sim 1700 K. The galactic kinematics of the host star are consistent with membership in the Columba association , implying a corresponding age of 30 ^ { +20 } _ { -10 } Myr . The system age , combined with the companion photometry , points to a model-dependent companion mass \sim 12.8 M _ { \mathrm { Jup } } . The host star ’ s estimated mass of 2.4–2.5 M _ { \odot } places it among the most massive stars ever known to harbor an extrasolar planet or low-mass brown dwarf . While the mass of the companion is close to the deuterium burning limit , its mass ratio , orbital separation , and likely planet-like formation scenario imply that it may be best defined as a ‘ Super-Jupiter ’ with properties similar to other recently discovered companions to massive stars .
