HD 284149 - Imaged sub-stellar companion

A new sub-stellar companion around the young star HD 284149

Even though only a handful of sub-stellar companions have been found via direct imaging, each of these discoveries has had a tremendous impact on our understanding of the star formation process and the physics of cool atmospheres. Young stars are prime targets for direct imaging searches for planets and brown dwarfs, due to the favorable brightness contrast expected at such ages and also because it is often possible to derive relatively good age estimates for these primaries. Here we present the direct imaging discovery of HD 284149 b, a 18-50 M_Jup companion at a projected separation of 400 AU from a young (25 Myr) F8 star, with which it shares common proper motion
