We report the discovery of a planetary-mass companion, HD?106906 b, with the new Magellan Adaptive Optics (MagAO) + Clio2 system. The companion is detected with Clio2 in three bands: J, KS , and L', and lies at a projected separation of 7.''1 (650 AU). It is confirmed to be comoving with its 13 ? 2 Myr F5 host using Hubble Space Telescope Advanced Camera for Surveys astrometry over a time baseline of 8.3 yr. DUSTY and COND evolutionary models predict that the companion's luminosity corresponds… Expand
